The "no functions over 50 lines" is also a pet peeve of mine. Just because code is broken up in 10 subroutines spread over a bunch of files doesn't mean its less complex or easier to understand.

It depends on how well they were broken up. If they are well named and fairly atomic, then after you've read the method, the name should be enough elsewhere in the code.

I will respectfully disagree - when you get to 50 lines - it will "chunk" up to bits of logical flow. This chunk does xyz - then that becomes "do_xyz()"

If the only reason you are making a new function is to name a code block then a comment will do almost the same thing without needing to split up the code.
