Description:
------------
I propose to add a special syntax (simplification) for a function declared with just one argument. The idea is to remove array with its brackets ( ) in the function call to improve readability and get rid of unneeded array keyword. This feature is expected by many people who use such type of functions as a replacement of the PHP's missing feature to specify function's arguments by name.

For example:

  function setParams(array $params) { /*...*/ }

Current call:

  setParams(array('name' => 'foo', 'width' => 300, 'height' => 150));

Proposed call:

  setParams('name' => 'foo', 'width' => 300, 'height' => 150);
