Very similar to Windows Structured Exception Handling, which the Win32 implementation used, and also looks similar to Java, but without checked exceptions. try/except/end and try/finally/end blocks.

The major differences with C++:

    * objects are references not values, cutting out all the copy constructor,
      assignment operator, destruction on out of scope etc.
    * objects are zero-initialized after allocation and before constructors run
    * constructors are run from most derived to least derived
    * calling Free method checks if Self is nil
    * this + zero init means that you can call '.Free' on all the objects you 
      reference in the destructor without checking if they're nil first, 
      handling partial construction

It's not a memory safe language, but it does give you a bunch of idioms that, if you stick to them, you don't feel nearly as much pain as C++.
