I either disagree with you here, or my statement wasn't clear.  In your 
code sample, in my opinion, everything not inside a function is run 
right when that script file is opened.  Things inside functions are 
saved for later parsing.  Thus, when it sees x = 5, it's in context of 
the already defined x (=10) and not in context of the order in which 
they were declared.  This it thinks that you're trying to set the 
global.  This is part of the reason I'm afraid of having code outside of 
functions... the order that it's parsed and executed is muddled (from my 
view, though perhaps it's clear to you).

Me too.

That's fine

Yeah, that's what I was thinking
