I must say I fully agree; I don't see any use in putting extra functions 
in the PHP namespace just because people don't want to type a couple of 
extra characters.

because, by definition, $LOCAL would at all times be a part of $GLOBAL. 
And besides, why would you ever want $LOCAL? $GLOBAL is a way to reach 
the global scope from the local scope. When being in global scope, you 
never *have* a local scope, and the other way around, when being in 
local scope, you can reach all variables directly anyway, so there's no 
use for $LOCAL. Then, expecting the response "why is there a $GLOBAL 
array in global scope?" you might want to say that $GLOBAL is a 
superglobal just because the "global" scope can be seen as a "local" 
scope in a broader perspective. Well... that's my view on it anyway...
