Just to save you some lookups in the Hack documentation: 1. Hack uses the "as" keyword: class Foo<T1 as Bla> {} 2. It does not allow to require multiple types for T1: "Currently, Hack only allows one constraint on a type or a method." 3. I found no example that Hack allows multiple type parameters like class Foo<T1, T2> but also nothing that it is not possible 4. All type parameters must start with a capital T 5. Hack has generic methods 6. Hack has generic traits which we should also consider/specify how they work exactly.
