--- Comment #3 from Andrej Mitrovic <andrej.mitrov...@gmail.com> --- Indeed this is not technically a bug at all, for example: http://dlang.org/spec/template-mixin.html#mixin_scope *However*, we could make it a compiler error to define constructors in mixin templates as they can't really be used in any way. --
