Hi,

About =E2=80=9C coercing NAN to other types=E2=80=9D:

* The result of `(string) NAN` seems reasonable to me and don=E2=80=99t need=
 warning.=20
* I agree that `(int) NAN` does not make much sense, but if we warn on that,=
 we should also warn on `(int) INF`, which makes even less sense (I expected=
 `(int) INF` to yield `PHP_INT_MAX`, but it yields `0`).
* I strongly think that this should be a deprecation, not a warning. There m=
ay be correct programs that rely on the fact that explicit coercing from a r=
andom scalar to another scalar type is infallible (as it is the case today),=
 although not expecting a specific value from a buggy input (GIGO principle)=
.
