Operating system:
PHP version: 5.6.4
Package: PHP Language Specification
Bug Type: Bug
Bug description:By-ref parameters with array/callable typehints should be permitted
Description:
------------
The language spec states this in spec/13-functions.md:
*parameter-declaration* must not contain `&` if *type-hint* is `array`
or
`callable`.
Yet PHP allows this:
$ php -r 'function a(array &$foo) {} $a = []; a($a);'
$ php -r 'function a(callable &$foo) {} $a = "strlen"; a($a);'
$
Why, then, is it prohibited in the spec?
