in thread Rules of Lexical Scoping

I personally believe that ysth has adequately answered that objection, but I would answer it this way: All of that happens under the hood; it has no user-visible effects. In any way that a perl programmer can tell, perl behaves just as ysth has described.
s/ysth has described/dave_the_m has described/.

Also "has no user-visible effects" is an overstatement; should have no user-visible effects is more accurate. The rules describe how things should work; there may be bugs, and (as in the case of my $foo if 0;) there are things you can (but shouldn't) do to expose rule violations that for various reasons won't be fixed.

    I presume you're alluding to this; I was merely referring to your root in this thread.

    Granted.
