Such a feature would fit nicely with the relaxation I refer to here, to allow wrapping lambdas in member constructors and similar.

It's problematic:

I think I can skate around this problem by applying the hammer of code
injection to this nail, by writing
a code injection metafunction that takes the initializer as an
argument, and then injects a member
of the result type of the initializer, and injects the initializer for
the member.
