It should actually be possible to implement Objective-C with the .NET
framework. Even categories should be possible to support.
In Objective-C method invocation is always done at runtime, and there
is very little support at compile-time for it. Every method
invocation is performed by the runtime.
For example, the compiler will translate:
[object someMethod: "hello"]
Into a call to a general message sending routine:
__msgCall (object, "someMethod", "hello")
It should be pretty simple to implement __msgCall, specially given
System.Reflection.Emit's capability of generating code on the fly.
Categories can be trivially implemented by having your `__msgCall'
function cope with it.
That does not mean that an Objective-C program will be immediately CLS
compliant at every level, but it is a start.
