I dunno, back in the old PHP days (like the really shitty PHP) if you missed a semicolon on an included file, and that file was included in another file, and some dumbass included that in the middle of some other file, you would spend hours looking for it because the error showed it missing in the top-most file.
I use the firefox password manager personally. Not sure if that makes me an idiot or not but it works well and I trust mozilla.
