I am (still) wondering whether there is something like apple's grand central dispatch for perl. perl seems well suited to it, too. Syntax could be something like:

sub runme {
  my $arg=shift;
  # do something very long that has no side effects
  return @stuff;
}

sub a { runme(1); }
sub b { runme(2); }
sub c { runme(3); }

my @results = grandcentral_like_runall( \a, \b, \c );

[download]
grandcentral_like_runall then runs these subroutines on as many cores as the processor has, and continues on only after all three are complete.

Does some package with this sort of functionality already exist?
