NAME
Error::Wait - user-friendly version of $?
SYNOPSIS
use Error::Wait;
system('/no/such/file') == 0 or die $?; # "No such file or directory"
system('/bin/false') == 0 or die $?; # "Exited: 1"
system('kill -HUP $$') == 0 or die $?; # "Killed: HUP"DESCRIPTION
Error::Wait overloads the stringification of $?. Numeric operations continue to work as usual, so code using $? >> 8 won't break.
KNOWN ISSUES
$?++ and $?-- won't work correctly.
