Re: [hibernate-dev] Do you know of any ASL 2 implementation of...

I haven't gone into supporting type variables, hence I don't perform type capturing or inference yet, although I would be interested in adding this. For an example of what is currently implemented, the following are from the tests: Number <: Integer Object <: Integer List <: List<Integer> Collection<Integer> <: List<Integer> Collection<Integer> <: ArrayList<Integer> List<Integer> !<: Set<Integer> List<Number> !<: List<Integer> List<?> <: List<Integer> List<? extends Number> <: List<Number> List<? extends Number> <: List<Integer> List<? extends Number> !<: List<Object> List<? super Number> <: List<Number> List<? super Number> <: List<Object> List<? super Number> !<: List<Integer> List<Integer> <: IntegerArrayList Let me know if you find any existing libraries since I use this in my other projects. If there's nothing out there then open-sourcing this would stop people from having to reinvent the wheel.
