Description:
------------
Since it's a complex problem, I would like to stir       
up some discussion about the best way to solve the       
ambiguity of terms between "variable functions" (i.e. a       
function call in which the name of the function is       
contained in a varable:       
http://www.php.net/manual/en/functions.variable-functions.php)       
and "variable functions" (i.e. built-in functions for       
handling varables:       
http://www.php.net/manual/en/ref.var.php).  In my learning 
and use of PHP, I have repeatedly encountered this term in 
both senses, requiring me to seek clarification of its 
meaning in contexts that are ambiguous.  Therefore, I was 
wondering if it would be possible to change one of the 
terms.  My suggestion would be to change the second sense 
to "variable handling functions" or something of a similar 
nature.  Such a solution would preserve the analogue 
between "variable variables" and "variable functions" (in 
the first sense) and is also somewhat 
backwards-compatable.  But I would like to know what 
others think. 
 
Any thoughts, suggestions on this issue?  Anyone else had 
problems with it? 
 
If a conclusion can be reached, I'd be willing to do some, 
if not all, of the work to update the documentation.
