To change a completely misunderstood citation into a new one that nobody will understand either:
> Unnecessary flexibility is the source of all evil
Just as with the original "premature", the word "unnecessary"is doing a lot of heavy lifting here, and there's no way to state that rule that saves people from thinking before applying. Some times those 10x SLOC are really important and will save you; most times it's just a 90% waste ratio multiplied over your previous one.
