> it's typed (now)

To note, you'll need strict mode for type hints to be useful. https://www.php.net/manual/en/language.types.declarations.ph...

The fun part is, instead of going for a generic strict mode system we would have expected, PHP went pragmatic: as most application won't be 100% strict typed, you need to declare it file by file, the icing on the cake being that the restriction applies on the caller of the functions, not the function itself.

It makes for complicated situations, where for instance you can make an utility class that is 100% typed and follows strict typing, but if the caller of your class isn't, none of it will matter and types will be fuzzily coerced anyway.
