RemObjects introduces several really interesting language features with the new version of their Pascal Dialect, which I think would be useful extensions for non .NET compilers, too.
Parallel Programming:
have multiple-CPU systems run code automatically in multiple threads
Property Notifications:
I suppose this allows for attaching multiple handlers to events (but maybe I'm wrong, but multiple handlers is a .NET feature (AFAIK) I suppose it's supported by Oxygene somehow and of course it's useful for non .NET programs, as well)
Nullable Expressions:
Calculations automatically handle a "missing value" bit-combination in a type (in fact not new with Oxygene 3.0 but a feature of Remobj's language since long) (I don't know if that uses .NET support, but of course it can be done natively as well).
Would it be appropriate to take a look at Oxygene and aim for implementing such advanced features in a compatible way. If there are copyright issues, I feel that RemObj will be much more communicative than CodeGear is :). I think that all worlds (native and .NET, "commercial" and "open source") will profit by advanced features and compatibility.
