PHP

Proper typing of nested or generic types. For instance: generic classes or array elements without phpdoc's template.

For me the typing of array elements is the most important one. As soon as you have some form of array, the typing in php ends. I see this as such a short coming in the growing type system of php. Seeing a lonely array type always leaves me questioning simple things like: What kind of array is it, a list of strings, objects? Or maybe an associative array? Does it even hold items? Why are we here?

I'm keen for this community to gain some traction, hopefully it's a bit less toxic than our reddit counterpart.

I would love to see Generics and custom Types in PHP. Generics for obvious reasons. And Types so we don't need to create a DTO just for type-hinting of objects. Combined with Generics, so we can have typed Arrays!

How about real threads?

There used to be some pthreads support, but it wasn't very good.

Also some native event IO support. I tried playing around with libevent, but was not very successful with it.

Right now the only reason I ever use php is because I have to.

This one simple change would bring me half way to wanting to use php for fun (the other half would be making debugging easier).
