Error::Wait - User-friendly version of $?
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"
Error::Wait overloads the stringification of $? to provide sensible error messages. Numeric and boolean operations continue to work as usual, so code using $? >> 8 won't break.
"$?" in perlvar, "system" in perlfunc, "system" in perlport
$? and the wait.h macros aren't very portable.
