NAME
    maybe - Use a Perl module and ignore error if can't be loaded

SYNOPSIS
      use Getopt::Long;
      use maybe 'Getopt::Long::Descriptive';
      if (Getopt::Long::Descriptive->VERSION) {  # run-time checking
        Getopt::Long::Descriptive::describe_options("usage: %c %o", @options);
      }
      else {
        Getopt::Long::GetOptions(\%options, @$opt_spec);
      }

      use maybe 'Carp' => 'confess';
      use constant HAS_CARP => !! Carp->VERSION;
      if (HAS_CARP) {  # compilation-time checking
        confess("Bum!");
      }
      else {
        die("Bum!);
      }

DESCRIPTION
    This pragma loads a Perl module. If the module can't be loaded, the
    error will be ignored. Otherwise, the module's import method is called
    with unchanged caller stack.
