Description:
------------
Currently to compare if a variable have some (?:exact)? value we need to use arrays or enumerate a list of all values + the variable name itself, Ex:

$a = true;
if ($a === 'a' || $a === 'b' || $a === 'c') # etc...
	print 'true';
else
	print 'false';

IMHO will be very very handy if we can evaluate them all in a single expression like this:

if ($a === ('a'||'b'||'c') # ...

is much cleaner and easier to read and understand the whole sentence


Test script:
---------------
$a = 'a';
if ($a === ('a'||'b'||'c'))
	print 'true';
else
	print 'false';


Expected result:
----------------
true

Actual result:
--------------
false
