Description:
------------
It would be pretty cool if you were able to use { CodeHere; } as Statement.
The Basic Idea behind this is like if the Code was a Function that had a Return 
Statement. Its only a little inefficient because the Function might only be used 
one Time, which means it would be useful to have such a Feature.

Examples are given in the TestScript

Test script:
---------------
<?php

  //1.
  if({
    $a = false;
    $b = true;
    return (time() % 2) && $b || $a;
  }) echo 'It equals to True';

  //2.
  mysql_connect(...) or {
    $file = fopen('ErrorLog', 'a+');
    ...;
    return die();
  };

  //3.
  $a = 12 + {
    return 2 * 2;
  };

?>

Expected result:
----------------
1. Depending on the Time echoing 'It equals to True';
2. When mysql_connect returns false that it evaluates the {}-Code
3. $a = 16;

Actual result:
--------------
Parse Error of course

Closures here should really be enough for what you are trying to achieve:
http://php.net/closures

As for the function-call-or-failure sample, if you really want such a context then I do not see why you don't simply do:

if(!call(...)) {
        ...
]
