When should clamp! be expected?

Hi @findmyway, I noticed you added clamp! to the readme. If I am implementing an agent, when should I expect clamp! to be implemented in addition to clamp. For instance, obviously I cannot expect clamp!(3, 1..1) to work, but I would expect clamp!(::Vector, ::Box) to work. In my code, how can I check and be confident that it will work?

My initial thought is, as long as the first positional argument of clamp! is mutable.

Ok, I guess that is the obvious answer :) I guess any space of AbstractArrays should have both clamp and clamp!` implemented for it.

Someone will need to go through the current code and implement clamp!
