Dear Monks,

I'm investigating the possibility of using autobox in my day-to-day coding. The first thing I did was look into the speed penalty imposed by the use of this module.

The preliminary results seem to indicate that a lot of the additional overhead is coming from the subroutine call when using autobox vs when using the CORE:: routines directly.

#!/usr/bin/perl
use strict;
use warnings;
use autobox;

sub SCALAR::uc { CORE::uc($_[0]); }
sub autobox1 {
    return "Hello, World\n"->uc;
}
no autobox;


sub primitive1 {
    return CORE::uc "Hello, World\n";
}

package main;
use Benchmark;
cmpthese( -1, {
    'autobox1'   => sub { autobox1()   },
    'primitive1' => sub { primitive1() },
});

cmpthese( -1, {
    'autobox2'   => sub { return SCALAR::uc( "Hello, World\n" ); },
    'primitive2' => sub { return   CORE::uc( "Hello, World\n" );   },
});
__END__
               Rate   autobox1 primitive1
autobox1   183794/s         --       -78%
primitive1 835106/s       354%         --
                Rate   autobox2 primitive2
autobox2    513912/s         --       -89%
primitive2 4797406/s       834%         --

So, I'm wondering what the feasibility of just having autobox use CORE::uc directly to do its magic rather than wrapping it in a sub and incurring the corresponding overhead.

I've tried using differnt combinations of import options as well as a sub class and hacked up version of autobox.pm thus far but to no avail.

Thanks everyone!
