No dynamic class creation. Dynamic class creation is useful, but requires a compiler or interpreter be present at run-time. What is a proxy for a class? Bill

It's for RPC mechanism.
If I want to do write a remote object mechanism I need to have some local
object (called proxy) which act
locally as an instance of a given object but when its method are called, it
write to a sockect an encoded version of the method call, which is decoded
by the server at the other side, which call the corresponding object and
respond with both (or either) the exception or return value, decode locally
by the proxy, then returned.

      Proxy               Internet             RPCServer    ServerObject
+ ---------------+----------------------+----------------+----------------+
 | myMethod() |--> "coded call"--> | decodeCall() | myMethod() |
 | decodeRet()  |--< "code ret"  <-- | encodeRet()  |

for this I would need a way to create dynamic instance or, at least I need
some concept like interface.
either I write a generator of InterfaceProxy code or create them dynamically
(if possible) is not so important, but to be able to create them dynamically
would be nice ....

No dynamic class creation. Dynamic class creation is useful, but requires

 compiler or interpreter be present at run-time.

 What is a proxy for a class?

Uh... Do you mean dynamically create a new class object? By proxy, do you mean an object alias perhaps?
