Re: phantom subroutine parameter values

[blahblahblah]

in reply to phantom subroutine parameter values

This will happen when you call a sub with an ampersand but without any parentheses, like the following:

⊂

Doing so makes the calling sub's @_ visible to called subroutine. To avoid this, either omit the ampersand or include empty parens when calling a sub with no args. See perlsub for more info.

Thanks guys. I knew it was something simple... That explains why a lot of my old code doesn't have ampersands... Sucks be forced to program in tcl for a few years... rpelak

uh?! it seems a feature! in any case i like calling with the & 'cause i spot easy subroutine's calling.

if i understand :

sub refinemydata
   {  my $data = shift;
      &is_refined:return?&rerefine;}

could be a valid syntax too ?

The ampersand is functional, not decorative. &func(args) is not the same as func(args). The function's prototype is ignored in the former. And &func, &func() and func() are all different. @_ is left untouched by the first.
