+1 on *not* removing the warning. I can't see any reson why it should be
removed.
php -r '$foo = array(2, 3, 4); echo substr("foobar", $foo). "\n";'
currently prints "oobar". Would like to see, as Jani suggested, E_STRICT
notice thrown when wrong data type is passed to a function/language
construct.
