PS C:\Users\user\Desktop\source> dmd -run m1.d sub/package.d sub/m2.d
m1.d-mixin-9(9): Error: static assert  __traits(compiles, sub.m2.Bar.bar) is false

While fullyQualifiedName is able to find the symbol Bar, __traits compiles does not find it. It works if I replace the package.d import with the specific module m2.d import
