Their use is discouraged at this point, but they're used by so
much code that I'd be very surprised if they were ever

compare non-string lambdas for equality, they're _defintely_
not going to be deprecated. Regardless, AFAIK, neither Walter
nor Andrei has ever stated that they will be removed from
Phobos - just that we want to move towards using the newer
style lambdas instead.
Besides, `reduce!"a+b"` and `map!"a*a"` are more concise than the
lambda versions and can therefore be preferable in some
situations.
