Bug description:Emit notice for NOP statement

Description:
------------
As a matter of convenience for PHP programmers, would it be possible to
somehow 
detect NOP-type statements (see example below) and create a new notice to
notify 
the programmer of their presence?

When writing embedded code, NOP statements are often handy (or even
required). 
However, in something as high-level as PHP, I can't see any situation where
one 
would need such statements. Thus, whenever they DO occur it's most likely
by 
accident (again see example below).

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

"This string was meant to be sent as output, but I forgot to echo it!";
1+1;
$variable;

?>

Expected result:
----------------
Notice: Statement has no effect in (path) on line 3

Notice: Statement has no effect in (path) on line 4

Notice: Statement has no effect in (path) on line 5
