instantiation ?
Do you mean mixin-expansion ?
or are you talking about mixins created in templates ?

Although Caching mixin expansions hits on the same problem as 
chaching template-instances, it is more difficult since a mixin 
can appear anywhere.
and one has to worry about a much wider scope.

I'll see what I can come up with, for now the debugging is 
priority.
@Ethan can you share code illustrating your usecase.
(My head is inside compiler internals and building test-code is a 
rather unpleasant context switch)
