Message:

Major exception update, seperating type-ids from virtual tables. The major interface changes are done. There is a regression of ?Cancelled(T) to Some?Cancelled. There is some bits of code for the new verion of the ?Cancelled(T) interface already there. Not connected yet but I just reached the limit of what I wanted to do in one commit and then spent over a day cleaning up, so it will replace Some?Cancelled in a future commit.
