Topincs needs an extension for programming. It should be easy to learn and the programmer should be freed of any infrastructure problems being able to focus on the domain.
Tackled one of the main issues: objects based on topics without programming using TM/JSON. PHP's __call comes in handy. Extending such objects is very easy and has next to zero infrastructional bloat, focuses on the domain.
Tackeld the multiple inheritance problem. An object will have access to all methods defined for its types. No matter how many types it is an instance of. And how many super types those have.
Tackeled the issue of parameterizing services including making them accessible from topic pages.
