The Tutorial has a few sentences on lambda, and (IMO) neither over- nor
under-sells it as is.

What horrors?

The standard library has many appropriate examples of Python lambda use.

I wouldn't want anyone putting down the functional folks, but I'll refrain
from worrying about that until I see it happening.

Sorry, I really don't know what you're on about here.  If Python's lambda is
showering the functional programming community with bad press, it's news to
me.  To the contrary, on the Tutor list I've seen several new programmers
inspired to look into Scheme and Haskell precisely because Python lambda
intrigued them.  There's nothing bad about that.
