Bug description:Allow multiple comparisons in expressions
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
