( #3333=superdoc: print w/replies, xml ) Need Help??

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")

    [Corion]: Meh, first round of escalations for me not wanting to fix in production what a project has mismanaged. Now another project, which eats up all the resources until end of this year wants to take that task and put it on my list of things as well.
    [Corion]: So now there will be the fun of me explaining to the project that $other_project had low priority because $project has high priority. If $project picks up the task from $other_project, they also will need to reprioritize my tasks to get that done...
    [Corion]: ... of course at the cost of something else on my list of tasks for $project, as there only is a finite amount of days until $deadline.
