I use it all the time, generally in two cases:

 - as an argument to mapcar (analogous to a map/lambda in Python)
 - when I'm adding a hook and don't want to bother naming it.

I think that the more functional of a programming style you have, the
more useful it is.

It's not a reserved word.

(let ((lambda 3)) lambda)
=> 3
