Yes but ... if it is such a small function containing just a few
lines, chances are it is something basic to you and your way of using
Emacs, and if it is, chances are, further, that you will want it
again, but from a slightly different setting, e.g., another
major mode.

If and when that happens, to avoid duplicate code, turn the lambda
into a defun and call that from two places, rather than
killing/yanking the original lambda...

They seem to have a different focus, namely how to call it.
This makes sense as, having no name, I mean, yeah, how do you call
it?!

Again, see the note here on lambda docstrings:

  C-h f lambda RET
