Description:
------------
This is a low low low priority feature request, but it would be nice if the range() function supported letters beyond just A to Z. 

For example:

echo count(range('A','ZZZZ')); 

returns 26, but in many other languages once you get to Z it continues to AA

For example in perl: 
perl -e '$_=()=A..ZZZZ;print'

you get 475254



Test script:
---------------
$a = count(range('A','ZZZZ')); 

if ($a == 475254 ) { 
  echo 'RANGE IS WORKING!'
} else { 
  echo 'RANGE STOPS AT Z. Foo. '
}

Expected result:
----------------
RANGE IS WORKING!

Actual result:
--------------
RANGE STOPS AT Z. Foo.
