No successful language has every possible feature.  The ones that have tried (e.g., PL//1, Ada) have had very limited use, I think.  I'm guessing you've never heard of either of those. 

Imho the best languages have a consistent point of view, some central idea around which everything is organized.  In BYOB it's first class data.  We haven't gotten anywhere near a fully consistent point of view, but we don't want to move backwards by adding something that's clearly counter to our pov.

I'm sure we'll be adding plenty of new stuff, but it'll be first class _____ (fill in the blank) rather than low level "what's where in memory" stuff.

how bharvey is not including an 'important programming concept' suggested by nXIII.

Hey, no fair; we've taken plenty of ideas from you guys generally and nXIII in particular.

I'd be happy to see a proof-of-concept Scratch extension that demonstrates the kind of program you can write using pointers that you can't write better without using pointers.  That's what we did in the movie!

Pointers are important if you're writing a compiler or an operating system, but not if what you're writing is an application, like most Scratch projects.

P.S.  One procedure that sort of calls for pointers is SWAP <x> <y> where the two inputs have to be variables.  But a better solution to that particular problem is one that nXIII was himself working on for a while, a generalized SET block onto which you could drag anything settable.  I'm not sure what the status of that project is, but it's an example of how to do what pointers can do in a cleaner way.

Uh-oh, I think I just did.
When you save a project, any variables that have been set to a script report the script's tuples (y'know, asBlockTuple?)
Make sure that any block tuples stored into a variable get transfered into the script in 3.1.

lol. you should see my desktop. I've made SO many downloads (95% Scratch projects, 4% Scratch mods, and 1% not-Scratch-related) that my desktop can't display all the files.
I like my Scractch mods too.
BTW, those letters on your desktop spell out PANTHER, don't they?

No, actualy they don't, A while back I was working on a project, never finished it, called Fleet Commander.

@Bharvey Well... we kinda do... its just that I don't really like having folders on my desktop, I geuss if my desktop gets TOO cluttered i'll do that, but... its not that bad at the moment.

LOL, I dunno about that. I suggested the show/hide list block (along with countless others, I'm sure) during the 1.3 beta program and they're only getting around to that now! 

Yay, it is!
But fullmoon's is so much cooler than mine.    Great job on it!

Glitch: I had such a long script in the make a block window, that the hat block I was going to join it to disappeared!
Also, I accidentally double clicked a custom block with an infinite loop. How can I stop it from running?

That's not the point of BYOB. 

Just tell that to the Scratch team.

I've noticed that you can put a reporter in the drop-down-box of list and variable blocks, but you can't put one in the "key [] pressed?" block!

Was that accidental or deliberate?

Here is a link to a larger version.

After which everything I did gave me an error message. I went to presentation mode and back out to see if it would fix it, and then all I had was a blank screen.

You probably won't be able to reproduce it, but...

That is . . . strange. o.O

escape-click

Doesn't work with separate blocks. I managed to get out of it eventually though. I'm not sure how.

Just list blocks, not variable blocks, if you mean SET and CHANGE.

When we added first class lists, what we really wanted to do was eliminate the "Make a list" button altogether and turn the list dropdowns into List-type input slots.  ("Make a list" would be replaced by "Make a variable" and an assignment of a list value to the variable.)  We didn't do that to maintain compatibility with Scratch projects, so instead we made those ambidextrous slots; you can choose a named list from the pulldown or you can drag a list valued expression into the slot.  This wasn't a general principle about all dropdown menus.

Of course BROADCAST was already a similar special case in Scratch.

P.S. Hi from Boston!

That makes sense, although it's a pain. I was trying to shorten some giant scripts of mine, and ended up making it twice as long with custom blocks!

Cool! Are you going to make a stop at MIT? Are you going to shove a copy of the BYOB3 program in their faces shouting "IT WORKED! IT WORKED! IN YOUR FACE!" while cackling madly?

That, would be hilarious.
