But, assuming there is a use case for it, what if you want to
restrict to a type that is either boolean, or a struct/class
that can substitute for boolean - how do you do that without
using the "private" BooleanTypeOf thing?
In that case you can just write `is(T : bool)`.
Assuming it would substitute, that should probably be used on
this page in place of BooleanTypeOf since BooleanTypeOf is not
supposed to be public:
"enum isBoolean(T) = is(BooleanTypeOf!T) && !isAggregateType!T;"
