Description:
------------
Variable functions would be nice.

Especially seeing that this works:

class Test {function mb_strlen($v){return mb_strlen($v);}}
$type = 'mb_str';
$obj = new Test;
echo $obj->{$type . "len"}($type);

Reproduce code:
---------------
$type = 'mb_str';

echo {$type . 'len'}($type);

Expected result:
----------------
6

Actual result:
--------------
Parse error: syntax error, unexpected '{' in Command line code on line 1

Look at this:

<?php
echo call_user_func('mb_strlen', $type);
echo call_user_func_array('mb_strlen', array($type));
?>

You can also do something like this:

<?php
function MyBrandNewFunction( $Param1, $Param2, $Param3 ){}
echo call_user_func('MyBrandNewFunction', $Param1, $Param2, $Param3);
echo call_user_func_array('MyBrandNewFunction', array( $Param1, $Param2, $Param3 ));
?>

But working like that would be nice too.
