[PHP-DEV] [RFC] Keep type of reference params

[Manuel Canga]

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 ) {

    $array = "string";

}



$array = [ 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. 

However, I think it should be an error or exception when a string is assigned 
to $array var. 

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
