Since further down in the thread you seem to say that other modules would be acceptable: I use Data::Dump::Filtered for these kind of things. Since in this case Math::GMP deals with integers, I think it's probably safe to not worry about escaping the stringified objects, but in theory one could use the pp function for escaping values as well.

use warnings;
use strict;
use Math::GMP;
use Data::Dump qw/dd pp/;
use Data::Dump::Filtered qw/add_dump_filter/;

add_dump_filter( sub {
    my ($ctx, $objref) = @_;
    return { dump => "Math::GMP->new(\"$objref\")" }
        if $ctx->object_isa('Math::GMP');
    return; # normal dumping
} );

dd( Math::GMP->new("123"),
    Math::GMP->new("546745634563453111035453452346") );

__END__

(
  Math::GMP->new("123"),
  Math::GMP->new("546745634563453111035453452346"),
)
