Ok, If those two are true, then using it should be
considered for big files.

I don't think that shorter codes are always the
most efficient. They are nicer, but you can't
assure that they are faster. For example a simple
sort algoritm implemented with two anidated loops:
It is well known that you can use trees or other
strategies to achieve better results; however,
some of them are larger as the loop implementation
