Is there some way to declare a custom attribute inline?

For example: sub mysub($) : modifies { }.

My goal is to be able to tell myself that a sub I didn't necessaraly write wants a reference, without attempting to use the prototype for more than detecting the number of arguments. In this case, I would use prototype() and attributes::get() to determine that it needs one argument, and it needs to be able to modify the original, hence, needs a reference. If anyone can suggest a better way, please do so.

Whenever I attempt to follow the example posted above, perl rejects the attribute as invalid... which it is... but it is only invalid because it isn't a built-in, the syntax is acceptable...


My code doesn't have bugs, it just develops random features.
