# A variation on Errno's POD example: use Errno qw( ECHILD );

:) Unless you need the number/constant, you don't need to import from Errno

Also, you don't need to actually use Errno;, using %! in your code will load Errno for you

    Thanks for the tips. :)

    The updated code (removed the 'use', and of course the import):

    # A variation on Errno's POD example:

# ........ Do your stuff ........

if ( not close $something ) {
  if( not $!{ECHILD} ) {
    die "Houston, we have a problem: $!";
  }
  else {
    # Silence is golden; ECHILD is silent.
  }
}
