• template <typename E, E V>

  bool EnumIsValid ()

  Template magic to parse __PRETTY_FUNCTION__ and detect if `V` is a valid enum val of type `E`.

  A valid enum val will result in a __PRETTY_FUNCTION__ like:

  constexpr bool escher::internal::IsValidEnum() [E = MyEnum, V = MyEnum::kValue]

  whereas an *invalid* enum val of 999 will result in a __PRETTY_FUNCTION__ like:

  constexpr bool escher::internal::IsValidEnum() [E = MyEnum, V = (MyEnum)999]

  After stripping the terminating "]/0", it iterates backward from the end until it finds something

  non-alphanumeric-or-underscore and trims that prefix. For an invalid enum, the resulting string

  view will be a number, therefore the result is false.
