Okay. That explains the code, but now begs the question, why is it so?

I can think of two or three situations where I would like to use a pre-declared loop variable in a for loop and have it retain it's value afterwards.

What I cannot think of, is any benefit for it not doing so, nor any major/common caveat that it avoids.

Is a pre-declared, lexical loop variable localized (something that you cannot ordinarially do) for the loop body duration, for a "least surprise" or other DWIM benefit? Or is it simple a side-effect or caveat of the implementation?
