[Boost-users] Using bind / lambda to create a functor that (1) ignores arguments, and (2) returns a constant

Is there a way to use bind and/or lambda to create a functor that:

(1) Takes as input a single argument (that is ignored), and
(2) Returns a constant value.

Ideally, something along the lines of:

bind(constant(5), _1) // _1 is passed but ignored.

Thanks,
