alt Hacker NewsThat's exactly it but PHP Core refuses to address the typed array issue in wait for a consensus on Generics even though those two things serve different audiences.
I haven't actually run into a single issue with PHP's type system in the last few years. Literally the only thing that remains is typed arrays but that seems to be ways off due to fragmentation in how the core devs want it handled.
With how good PHPDoc and Phan are these days I don't really think about it anymore. You can sort of have typed array by implementing Iterator, Countable, ArrayAccess, and optionally Indexing but I assume you mean defining types of array values.
