There also seems to be a regression regarding mixin templates – I'm getting »Error: not a property s.isSetFlags«, where isSetFlags is a plain field (i.e. not a @property) of s added via a mixin template, but as the error occurs deep inside CTFE-generated code, I don't yet have a test case for this one either.
