One of the great things about Django/Rails (and I guess Laravel, but I have no experience) is the ecosystem of packages that integrate well with them.
For example, with Django, there are a ton of packages that integrate well with things like Models, the Forms subsystem, Middleware, Template rendering, Cache backends, etc.
Is there a similar ecosystem with IHP? Are the extension points there in the framework to allow those sorts of packages to integrate seamlessly?
My past experience with Haskell web frameworks was that there weren't many packages for common things, and that when there were they took quite a bit of integration work to use nicely.
