>>Over the years I've seen maybe half-a-dozen cases, in other peoples' code, where the programmer carelessly used different cases when referring to the same variable or other symbol name in a case-insensitive language. The code was always sloppy, so now it's a real "Danger, Will Robinson!" signal to me.

If you code like your language is case-sensitive, even if it isn't, you never get burned.

Unlike Sergey, I type with both hands and very fast.
