This is why I wanted to work on "as" part of the pattern matching. It
isn't clear what will happen with the actual pattern matching RFC
(yet), but being able to do:
some_function_expecting_int($_GET['foo'] as ?int);
And how about:
some_function_expecting_int(\intval($_GET['foo']));
And moreover, I'd write something like this, but:
function validate_int(mixed $value): int {
if (null === $value || '' === $value) {
return null;
}
if (\is_int($value)) {
return $value;
}
if (\is_string($value) && \ctype_digit($value)) {
return \intval($value);
}
throw new \InvalidArgumentException("What what!");
}
some_function_expecting_int(validate_int($_GET['foo'] ?? null));
But the example might be erroneous, I see your point, nevertheless making coercion explicit doesn't seem really relevant to me, the one point I like in your syntax would be null handling.
