For the sake of consistency, please take into account this example, which
works in the current implementation of PHP:

$b = 1 + "1";     // no error, $b == 2
$b = 1 + "House"; // no error, $b == 1

So, I believe that, raising an error or not, is not a question of the new
RFC.

Should there be an error, then it has to be in every unsuccessful type
juggling, regardless of the final assignment to a type-locked variable.
