Oh, my bad: I totally forgot a crucial thing on question: I want
this to work with a static member, for example, call myTemp like
this myTemp!(C.a) I don't mind if I to pass the type as parameter
somehow, like myTemp!(C, C.a) or myTemp!(C)(C.a) but I do need to
pass a symbol as parameter, hence I'm using alias template
parameter.
