Filter operates on AliasSeqs, not arrays. That's why I restated the __traits(derivedMembers, T) part, but this could just as easily be done by changing this line:

    enum members = [__traits(derivedMembers, T)];

to:

    alias members = __traits(derivedMembers, T);

Works beautiful, thank you very much!
