Makes sense =E2=80=93 then conversion from lists to arrays would happen the=
 same way

$some_int +=3D $some_float

converts $some_int to a float.

_If_ there was a list type then it would make sense to add a corresponding
is_list runtime check, and users would be able to typehint their functions
as returning a list, and get an error if the function actually returned a
(non-list) array.
