I've searched Mantis a bit and stumpled upon this bug report:

Well, operators involving only combinations of ordinals, enums and strings.

Is this the case for sets as well?

The following are the cases that I'd like to overload:

SomeSet := SomeLongInt (converting a C-style flags int to a set)
SomeLongInt := SomeSet (converting a set to a C-style flags int)
SomeString := SomeSet (for writing a set to console)
