I thought a bit on possible patterns in D to accomplish the
same without string mixins.
For example, defining the prototype `Foo_` then mixing in
`mixin MyMetaclass!Foo_ Foo`.
Got stuck trying to 'forward' (or copy the implementation of)
functions in `Foo_` into `Foo` after modifying them, though.
Besides trying to do it in D (please try still!), what do you
think of the idea? In general and say versus a robust macro
system with some level of access to CTFE? Or even just a good
macro system (someone began discussing this on the reddit
thread; talking about Racket macros).
Quite a lot of it seems doable with mixin templates and UDA
reflection.
Ethan Watson's dconf talk is a good point of comparison.
