value dispatch on enums?

I think static dispatch is getting confused about values versus
variables when binding arguments within the body of a method:

The code:

    enum Signal { High, Low, X }
    Signal `&`(Signal, Signal);
    `&`(High, x)    = x;
    `&`(X, x)       = X;
    `&`(Low, Low)   = Low;
    `&`(Low, z)     = z & Low;

The error:

    ~/nice/src/com/megacz/test/Test.nice: line 8, column 19:
    Ambiguity for symbol Low. Possibilities are :
    com.megacz.test.Signal(Low) Low
    com.megacz.test.Signal(Low) Low

It looks like Nice is trying to decide "which" Low to return when in
fact it doesn't matter (in fact since they're Enums, they must be both
.equals() and ==)
