If a closure has an argument and a used variable with the same name, PHP5 uses the 
variable; HHVM uses the argument.

The PHP5 behavior should be documented in the specification.

There's also an issue filed against HHVM to match PHP5's behavior (

Test script:
$foo = 'used variable';
$closure = function ($foo) use ($foo) { return $foo; };


Expected result:
'used variable'

Actual result:
PHP5: 'used variable'
HHVM: 'argument'

Not sure it is really necessary to specify, this doesn't seem to be an important use case. Is there any reason why it should be one way or another?
