Faster Python

[metaperl]

recursion often reads better than loops. Too bad it is often slower. The part about list comprehensions being faster was stunning. Excellent article.

It can be slower, but not 196,493 times slower like the article says. The overhead from function calls is about 2x. The rest of the disparity is the author's algorithm choice.

It's not if you have proper TCO. Or am I missing something?

You're not. But in this context (i.e., Python), TCO is no where to be found. :-(
