It's not a bug. The assignment is illegal, because a you can't
assign a ulong to a uint without casting, but the error message
obviously isn't very good. It probably gives that error
whenever you try and use the property syntax, and there's no
variable or function with that name that compiles with the
given argument. It really should be indicating that the
argument itself is invalid, but however the combination of
lowering and error messages works, you end up with a less than
helpful error message.
I figured as much. Very difficult to figure out the culprit when
it's from bitfields mixed with perfectly normal code for
assignment.
Where should I add to the bug tracker so the error message can
be improved?
