I wrote exe() and bg() for that purpose because I felt that IPC::* syntaxes were non-intuitive, IMHO.

Pipe processes and Perl subroutines together

Internally, both functions perform safe forking methods to ensure no child zombies.

Example to sort & number the list of /tmp files:

use Exe;

my @pids = &{
   exe qw(ls /tmp),
   exe qw(sort -n),
   exe qw(cat -n),
};
