[myhdl-list] Can't compare Signal(enum)

[Thomas H. <th...@ct...>]

I cannot compare signals containing enum instances; this looks like a 
bug to me:

 >>> import myhdl
 >>>
 >>> state = myhdl.enum("foo", "bar")
 >>>
 >>> a = myhdl.Signal(state.foo)
 >>> b = myhdl.Signal(state.bar)
 >>>
 >>> print a == b
Traceback (most recent call last):
