The only real problem I have with built-in lambdas myself is the lack of
polymorphic ones.
The fact they're quite verbose (unlike the very terse lambda or phoenix
v2) is something I dislike, but that I can live with.

For captures, I don't see how anyone would want to do anything but
capture everything by reference.

Unfortunately, the only decent way of overloading operator. I can think
of is to take a polymorphic function object that takes obj, arg1, ...,
argN and calls obj.name_to_overload(arg1, ..., argN).
Problem is, that's only usable if you've got polymorphic lambda expressions.
