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.
  }
}
