If b and c can only happen in case a happens, I definitely would write it like
that. (as opposed to the flattened version) But not because of a potential speed
gain but because it's most likely also clearer to read. (at least for me)
Three if-statements in a row are independant in my understanding. If they're
not, I would replace them with a switch/case, make use of 'else if' instead of
normal ifs or nest them as in your example. Which one of the 3 possibilities of
course depends on the concrete case.
Did you measure how much speed you gained in your case? And where approx are
these if-statements? (if they're not in eval, I can't image you would notice
_any_ speed difference)
