We know by now, and we could not care less. Please stop bitching

Actually, the translation is quite straight-forward, in particular  
compared to similar translation projects in other languages. If there  
is something specific you want to know, just ask.

What do you mean by "system compiler"? The (old) Squeak compiler? It  
indeed does handle block-local variables as method temps. Why is this  
a problem for Slang?

That would be a bug, I think, but it would not be high on the  
priority list. Would be a nice little project to clean that up I guess.

Not true anymore, at least for the Unix VM. SVN head works perfectly  
for me.
