Let's start with some background as to what's going on.

There are problems with the implementation. The decision of what any given TYPE ~~ TYPE should do is most often unobvious, inconsistent and/or disputed. The idea isn't to remove smart matching; it's to fix it.

Specifically, ~~ will be greatly simplified, as you can see in a proposal by the 5.18 pumpking. Decisions as to how two things should match will be done with helpers such as those that already exist in Smart::Match. 

... ~~ any(...)

Much more readable, much more flexible (fully extensible), and solves a number of problems (such as "When should X be considered a number, and when should it be considered a string?").

So, if you like the feel of given+when, I recommend that you use experimental to disable the warnings and convert your code to use Smart::Match. Smart::Match uses overloaded objects and/or code refs, and that will continue to be supported. I'm hopeful that Smart::Match will be updated if necessary should the details change.
