I wouldn't question utility but rather the implementation of the above. One thing I'd love to see is thing like handful!("struct", "class", "union")that does pre-process contents at compile time to speed up search. In other words it's possible to not only come close to a series of a == "struct" || a == "class" || a == "union" but surpass it.
Sounds like an enhanced tuple?
At the very least handful!(a,b,c) can take expression tuple and make x in handful!(a,b,c) lower to: return x == a || x == b || x == c; even for run-time variables a, b & c.
