Where do you get reduce from if it's not in the standard library?
That was "a" proposal for 3000. Its there, but its not on the
built-ins; ie., you have to import it. The confusion: why reduce, why
not filter, nor map? {rhetorical}
As for lambda I've no real interest in it, other than when copying examples
where it's used to (say) provide a key function.
This is one of my main points to Steven. In my experience "most" people
do not intend to use lambda for anything; they are trying to sort this
or that and don't quite know how to get the key right and some helpful
somebody gives them a key=lambda yadda yadda . They use it, and it
works, but they are scratching their head saying to themselves, "what it
that, how does it work, how can I understand it and on and on".
That is what we mean by confusing. Or another really great example is
this thread. Somebody asks about a language feature and somebody else
helpfully answers the question by providing them with a similar lambda!!
Its the programmer's equivalent of explanation by reference to a more
complicated analogy; which leaves the OP left with, "Thanks for all the
responses".

PS You are absolutely right, all the expanding double spaces become
very annoying when viewed on Thunderbird; it is exasperating, genuinely.
