3.0 feature request: nested calls

Something else not mentioned, which is a little nicety, is nested 
functions/procedures within other functions/procedures. This is like Eu's 
include files with local scoping within those files. The upsides to allowing
this
is total lack of namespace conflicts, and inherently tight variable scope.


procedure1()
--var list here
-- no code allowed here

function2()
-- uses it's own 
      or procedure1's vars
      or main globals
end function2

-- no code allowed here

procedure3()
-- uses it's own 
      or procedure1's vars
      or main globals
end procedure3

-- procedure1 code here
-- can call function2 
     or procedure3
     or any other normal call

end -- procedure1

Like i said, procedure1 can be moved to an include.e, with function2 and 
procedure3 local to that include.e file. It's just a thought. Possibly the scope
methods could treat the nested system a little differently <shrug>. I found 
apps ran faster if i used vars local to procedure1 with function2 and 
procedure3, rather than passing anything when i called them, and this 
nesting guaranteed nothing leaked from procedure1.
