Bitfield-style enum to strings?

Assuming a plain old bitfield-style enum like:
enum Foo {
optionA = 1<<0;
optionB = 1<<1;
optionC = 1<<2;
optionD = 1<<3;
optionE = 1<<4;
}
Does a function already exist somewhere to take an instance of Foo and
get a list of the switch names as strings?
Something kinda like:
Foo fooVar = Foo.optionB | Foo.optionD;
assert(
DOES_THIS_FUNC_EXIST(fooVar)
.equals(["optionB", "optionD"])
);
Seems entirely feasible, although my traits-fu is a bit rusty.
