I disagree with the porting from other languages argument...

such code in the wild, many coding standards would force the

minimal.
It's a sensible argument. What about "among"?

Since 'among' only is concerned with equality it doesn't suffer
from the open/closed interval complication... thus in this case,
the simplest solution is the best imho... 'in' sugar would not
add much to the readability.
if (a.among("struct", "class", "union")) { ... }
