Trying to cast an integer to an enum and casting bit field values fails with "Cannot convert to this type".
Enum example TEnumAsByte from UE, where .Value is unsigned char:
Type: TEnumAsByte<enum ETickingGroup>
Expression: (ETickingGroup)($.Value)
Bit field example:
Type: unsigned char : 1
Expression: (bool)$
Also oddly bit fields sometimes are displayed as integers and other times as chars:

As a tangent it would also be great to be able to specify the type as a regex or at least a simpler glob expression with captures, so things like templates/generics can be covered by a single type view.
