I have to agree with this comment. More often than not one-liner rewrites of even trivial functions are unreadable and can't easily be modified, all for the sake of having the appearance of elegance. It's more important to have code that is easily understandable and extendable, which isn't always the case with fewer lines of code.

For example I could write a massive list comprehension in Python in one line that could solve my problem, but it would be much more difficult to read and would be a pain to modify. I'd much rather work with the 10 lines of code it would take to actually spell it out.
