I'm not terribly keen, to be honest.
In any application, I usually have a handful of custom constraints
sitting in the application's lib/ directory - and I think that's the
proper place for perl code, not a config file.
If you really don't want to create custom constraints, you can simply
create a new package file, with a new subroutine for each constraint,
and add a Callback constraint, pointing to that package/subroutine:
type: Callback
callback: MyConstraints::get_url
Both your examples though, can already be done with the Callback constraint.
type: Callback
callback: Core::cos
type: Callback
callback: LWP::Simple::get
(as long as you have code somewhere that does `use LWP::Simple`)
