Ah. BYOB was a mod of Scratch, so it's implemented in Smalltalk. Jens wanted to make the Smalltalk code editable in block form as well as surface-level blocks, and that's what Edit Elements does: it makes a block-based copy of a Smalltalk method.
Ok.
It makes no sense to me, though. For example, what's
? And why doesn't the "goto sprite or mouse" block in the screenshot expand to fit the green block inside it?
Sorry, I never made sense of it either. :~/ You need Jens, if he feels like exhuming this. I think there was a documentation file somewhere in the distribution, though.
Had to search that up.
I'll check.
It's "Elements090224", if I'm not mistaken.
Yeah that sounds right.
