I cracked it:

Reason: I hade a failing unittest using it as

     auto xs = x.indexedBy!"I";

which I changed to

     auto xs = x.indexedBy!"Ix";

For some reason the mixin magic becomes confused when I equals 
"I".

Do you have any clues as to why?

Should we restrict IndexedBy to not allow I to equal "I"?

:)

Thx anyway.
