I disagree on that point. For a typical-size display, it's a reasonable
guideline. But just because your 1500-line function fits in a single screen
does not make it readable. In particular, if the function is deeply nested,
then it quickly becomes difficult to discern which code aligns with which.

A similar principle informs us that 70-100 columns is a reasonable line
length limit for readability even if your display can fit much more.
