Vedran Čačić <ved...@gmail.com> added the comment:
Mapping lambdas is always inferior to comprehensions, in fact the main reason
comprehensions were introduced was that mapping lambdas was cumbersome. (It
didn't work so well for filtering by lambdas, but that's another story.)
As I said, Py3K was beneficial since raw maps weren't eager anymore, but it
also gave us a print_function, enabling the new antipattern
[print(obj) for obj in mylist]
which wasn't possible before.
It's too late for Python, but a lesson for some future programming language:
procedures and functions are not the same. Function call is an expression
having a value, procedure call is a statement having an effect. Both are
useful, but conflating them is not.
