in thread Apply function "keys" directly to function returning hash

Hmm. Well, yes, this *does* get me the keys of the hash, but my intent was rather more general: I wanted to be able to call a perl internal function which takes a hash directly with a function call as a parameter, i.e. "somefunc func()".
But thanks anyways!.

    It's not an internal function, but it does work exactly as you describe: 
    #!/usr/bin/perl -sw

use strict;

sub somefunc(@)
{
  my $i = 1;
  grep { $i++ % 2 } @_;
}

sub func
{
  return (
      1 => "one",
      2 => "two",
      3 => "three",
      );
}

print join(" ",somefunc func());
