Re^4: Passing a hash plus some strings to a subroutine

Thank you hippo! That is exactly the case. Why is that not a PBP? I have good reasons for putting code before dealing with parameters in subs, like using IPC::Cmd to check if we can run an executable:

sub something {
  return 'oops' unless can_run('something');
  my %arg = @_;
  ...
}
