Subject: [RFC] Keep type of reference params

Hi internals,



I would like to present a possible new RFC( "keep type of reference params"=
 ) for your

consideration.



Firstly, an example:



```

<?php



function my_array_shift( array & $array ) {

=C2=A0=C2=A0=C2=A0 $array =3D "string";

}



$array =3D [ 0, 1, 2, 3, 4 ];



my_array_shift($array);



count( $array );

```



The result of this code is a warning( in count line ) because of $array is =
a string.=20

However, I think it should be an error or exception when a string is assign=
ed to $array var.=20

In my opinion, $array var would have to keep its type when function ends.



What is your opinion ? Do you see it useful ?

Thanks and I'm sorry for my English( I'm a Spanish ).

Regards
