Re^4: Looping through a file, reading each line, and adding keys/editing values of a hash by GrandFather (Saint) on Dec 05, 2013 at 20:47 UTC
I know its strongly favoured by many. I don't understand why. My strong preference is to use pre-increment where possible so the increment operator is more easily seen (trailing stuff is more easily ignored). But maybe I'm missing something important about the post-increment? A very minor consideration may be that the post-increment could be slower for some implementations that the pre-increment. The difference is so slight that it would be exceptionally unusual for that to be a consideration. True laziness is hard work	[reply]
