SPUG: routine in foreach iterator

[James Moore]

Not sure what you mean by "map the sub_call", but this sort of thing is 
normal:

for my $x (foo ()) {
   print $x;
}

sub foo {
  return (1,2,3);
}

Since foo() is being called in a list context the list that foo returns 
will be used for the for loop.

I'm not sure what you're trying to accomplish with @{}.  Braces {} are 
going to create a reference to an anonymous hash, and adding a @ is 
going to get you a syntax error.
