Does it exist a Modelica language interpreter?

I'm developing an educational application for interactive simulation of very simple models.

I'd like that the switching from connections editing to simulating be faster than the perceived now. As this switching involves compilation of the model, the process is complex and takes about 10 seconds even for simple models. As the application is for test an error, i'm afraid having to wait so many times is not good.

I'm wondering if using an interpreter I could have a faster response from editing the model and simulating it, and if it would allow interactive simulation.

1. Is there any option for this with OpenModelica?
2. Does anyone know if such solution exist outside OpenModelica?
3. Which steps should I follow if I had to build the interpreter based on OMC from source?
