> Haskel? Where are the libraries?
Well, I suppose the same drawback would apply to Pony. :)
As for libraries, what matters is if the desired use case is covered, not winning the App Store count.
There's Nim and D too, but I get the lack of big commercial backing could disqualify them.

What libraries are missing? The only issue I've had with libraries are that some client libraries are wrappers over C libraries and this makes static linking difficult (or seemingly impossible on a Mac)
A few years ago there was a lack of libraries in some areas but that's not the case these days.
But yes, if you're working on a modern PHP project, there's a lot to love: A solid module system, an enormous sea of high quality libraries, type checking, a really nice deployment and scalability story, decent performance, good tooling (IDEs, debuggers, etc.), a servicable C-style syntax. For many purposes (not all!) it's ten times better than, eg, nodejs. (Which might seem like a low bar, I admit...)
I quite like Typescript as far as syntax goes, but I think PHP 7.1+ is comparable. And PHP has a lot more support, libraries, and better tooling in my view. For example, my experience in node land is there aren't really any good ORMs; PHP has multiple, including one (Doctrine) which is easily the equal in my view of the highly regarded Python SQLAlchemy. Similarly with routing, frameworks, templating, etc., there's a huge amount of maturity on the PHP side that's missing from node.
The big question is going to be in the process model. Node has an event loop; PHP doesn't. For most purposes, I think an event loop makes writing good code harder to no real benefit, but in some cases (eg, acting as the endpoint for a ton of open websockets) it can be a big win. If you do need that, then you should probably lean towards node over PHP, and sure, why not use typescript? But for the general case, I'd still lean towards PHP.
(Then again, there's also a ton of other languages and frameworks. Just because PHP - or node - might be better than the other for some task doesn't mean there aren't a dozen more languages better than both.)
It's still the same as C, which is _not_ a solid module system.
Though it has improved dramatically.
The VO's I use trow exceptions when you construct them with some bad value. This is great because when you use for example a natural positive integer object you are sure it is one.
So now I have 'type checking' and more secure code in PHP.

And it is still the case with type declarations, that they make your code actually slower, because the runtime adds asserts in your code which gets evaluated at runtime?
What are the alternatives if you want something with type checking? Java? No, thanks. Haskel? Where are the libraries? C/C++?
I guess Typescript is the only alternative
