Kenji Hara <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution|--- |INVALID --- Comment #2 from Kenji Hara <[email protected]> --- With class types, the possibility of implicit class reference conversion from derived D to base class B is always determined in type system. In other words, conversion from immutable D to mutable B is a defined but disabled by default, and 'alias this' cannot override it. (Note that 'alias this' is invoked when the conversion is _not_ defined) So, 'alias this' never be considered in the case, and this is invalid issue. --
