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.
