in reply to Dynamically Changing Packages w/out Eval

Some funny code I wrote yesterday (the technique can be probably used for your problem too):

use Symbol qw(qualify_to_ref); use overload; my $stashref = qualify_to_ref("${namespace}::"); package tmp; local *tmp:: = *$stashref; overload->import('+' => sub { my $self = shift; my ($other, $info) = @_; # do some stuff });

This sets up overloaded operators for the namespace with the computed name $namespace.

Note that you cannot use "main" instead of "tmp", because the main namespace seems to be too read-only for this kind of hack (you'd get the error "Modification of read-only value attempted")
