Re: subroutines and python status

Hey all,
What seems natural to me is to define 
subroutines in the middle of the code 
as I walk the parse tree:


You can do that:
.sub __main__
  bsr _main
  end
.end
.sub _main
    .sub _f
        print ":)\n"
        ret
   .end
    .sub _g
        print ";-)\n"
        ret
   .end
   bsr _f
   bsr _g
   ret
.end
So you have just to emit code, to call your real main at the beginning. 
You could also have a look at docs/calling_conventions.pod, which 
currently is being implemented. But if you have your code generation for 
subs/params/return values in one place, its for sure not complicated to 
switch calling conventions later.


Incidentally, I spent all day working on pirate,
and it now generates (and runs!) code for a bunch
of python structures:
Wow.
