alt Hacker NewsThe "good" rules are like "don't write off the end of an array", and the bad ones are like "no early returns" or "variable names must not be longer than 6 characters". 95% of the "good" rules are basically just longer ways of saying "don't invoke undefined behavior".

Why is "no early returns" not a good rule?
I do early returns in code I write, but ONLY because everybody seems to do it. I prefer stuff to be in predictable places: variables at the top, return at the end. Simpler? Delphi/Pascal style.

My memory might be lapsing here, but I don't think MISRA has such a rule. C89/C90 states that _external_ identifiers only matter up to their first 6 characters [1], while MISRA specifies uniqueness up to the first 31 characters [2].
