Looks like just a Perl problem -- you must use strict (i.e. my $val)
and reference $val instead of val in your call. Also, you must have
that in a BEGIN block to pick it up, otherwise you will have to
call the globalsub before it is defined.

GlobalSub <<EOR
sub new_filter {
    BEGIN {
	package Vend::Interpolate;
	$Filter{reverse} = sub {
			    my $val = shift;
			    return scalar reverse $val;
			    };
    }
}
EOR
