I like to build structures using template mixins because one can pick and choose functionality at compile time, but still have a relationship between different types.

It would be really nice if one could sort of test if a template mixin was "mixed" in(or ideally, struct S : SomeTemplate (template inheritance)).

While one can overcome a lot of the issues by doing static checking(e.g., does IsSomeTemplate compile or other introspective like checks), it is a bit messy and clutters up the code.

Does anyone do stuff like this and have a nice elegant way?

I suppose you could have the template mixin define a unique key ( kinda like the current(?) std.random's isUniformRandom trick) for that mixin and then do is(hasMember!(S,someUniqueTemplateMixinName))
