Now, if lambda was more than an expr, dumping "lambda" keyword would be a convenient idea -- unnecessary keywords can make the language less clear in some cases. One could do with Python's plain and simple "def", like this:
filter (def (x): x*2, myseq)
(Disclaimer: Without thinking further I'm not sure whether the above syntax would be unique enough, Python grammar-wise.)
If you'd like to think further about it, check the archves -- there's about a million different arguments about this. A recent brief one (2 days ago):
