Ada allows enumerated types whose member names are overloaded. You resolve
the ambiguity by specifying the type in ambiguous situations. The syntax
is <type_specifier>'(<expression>) in Ada (though I'm sure Ada uses
different names for the metasymbols).
car_colors is (red, blue, brown, black);
bike_colors is (orange, red, green, white);
. . .
x := car_colors'(red);
There was a certain amount of discussion of how this ought to be done in
SIGPLAN Notices in 1981 or so, but I havn't bothered to go look them up. As
I remember, the papers were mostly picking on Ada because it was very stylish
to pick on Ada back then. Now it is stylish simply to ignore Ada.
