The point is: let the variable name reflect what it contains, don't re-use the same variable for something else. That way your code will be a lot more readable. let fooline = "one,two,three" let foowords = split(fooline, ',')
Fair enough, but in most of the cases where this came up, I never really cared about the 'fooline' variable. It only existed as an intermediate to 'foowords'. My choices were either: 1) put everything in one assignment, which can get long and messy and harder to read, or 2) split it into two assignments by declaring an extra 'foowords' that I never really care about. Reusing the variable makes sense to me in this case, and this seemed like a harmless and logical addition, but I guess you're the Bram.
