No, it's very powerful and used in other languages, too.

The purpose of a print() function has been discussed for at least 3
years. You are welcome to read up all dicussions.

Wrong and wrong.
map stays but it has been turned into an iterator. The removal of lambda
has been discussed several years ago but it was repulsed. lambda stays.

Python 3.0 is even more beautiful and more Pythonic. Backward
compatibility was broken for the sake of the language.

Your truth turns to be a totally different truth than mine -- and most
of the active member of the community.
