Right, that brings back some memories.

Right.
: exit -> "leave program" (or is it "thread"?)
Hmm. Dunno. I'll assume thread for now

"last" almost works, except it's specific to loops
But last also works for anonymous blocks, which aren't loops. (Aren't they?
Don't know about you tovarisch, but my anonymous blocks execute just once.)
In fact, that's why I asked. I have a lot of code that

return -> "leave sub"
exit -> "leave program" (or is it "thread"?)
break -> "leave loop" (this is shaky: does it deserve to be here?)
last -> "leave block"

Except that by the current rule you can only C from something
that is declared with the word "sub". ->{...} is still just a fancy

why not use -> to create a sub which you can return from?

I don't see why we need it offhand. But we might well have something
that returns out of the innermost {...} anyway, so yo
