Re: [Boost-users] [phoenix] [clang] error assigning function object

`lazy_assign` is a phoenix actor, whose `operator()` will take the first argument by const reference and assign it to `foo`. But it is also a phoenix actor like `phoenix::ref`, so:

lazy_assign = (phx::placeholders::_2);

tries to create new phoenix actor (lazy function), whose semantics are really confusing (and thus an error is likely appropriate).

I just realized this is valid code since `operator=` returns a reference to the left-hand-size. Although, its still an odd expression. Lee
