This sounds very similar to what you are doing. I never really
looked into it, because I prefer to know which type is used
and give me errors if I try to do stupid things, but I think
it's a cool idea.
No, this is not what I'm talking about, although maybe it could
be related in some way.
Actually, it sort of is. Your mapEnum is essentially the same as
std.variant.visit (https://dlang.org/phobos/std_variant#.visit),
and std.variant.Algebraic is the type that encapsulates both the
runtime tag and the void[] containing the data of unknown type.
Now, there may be many important differences - Algebraic
encapsulates the data and tag, which may or may not be what you
want, visit only takes one algebraic argument, mapEnum may be
faster, more or less generic, etc. The idea of converting a
run-time value to a compile-time value is the same, though.
