This is fun!

At least we're likely to get a compile-time error if we try to use
operator== in Lambda like we would in Bind. Of course, WWLD? Would Lambda
support some similar form of operator== (perhaps by a
conversion to safe_bool?), or perhaps unlambda()'d function objects would
be EqualityComparable?
