Is this really what this is all about? removing that word? I do think that
adding a parens around the parameters would make it a bit more clear, but
it currently illegal:
In [18]: lambda(x, y): x + y
File "<ipython-input-18-0f5b071bce98>", line 1
lambda(x, y): x + y
^
SyntaxError: invalid syntax

There seems to be a frequent objection to the word "lambda" -- personally,
I found it cryptic, but it's not hard to remember, and it IS easy to look
up. But if you don't like that word, why not "def"? Every place I've tried
to use "def" where "lambda" is legal, it's a syntax error. So we could use
the same word. Would that be less confusing?
My thought is yes it would , IF we were stating from scratch -- but this
would be a lot of churn in code and documentation for very little gain.
