The distinction is that in a bitfield A|B is valid value to pass, but
that is not a valid value to pass for an enumeration. Bindings really
want this information.
This information must be on the enumeration itself, not on the argument.
I don't know of any language where the validity or return type of doing
A|B depends on where the expression is being used.
