try_python was one of the things that inspired me to write Crunchy. > Apparently you can't define classes or functions with TryPy, but I recall you > can using Crunchy.

In a classroom environment, you can even write some doctests that have to be satisfied by the student's code. One example included in the documentation requires the user to define a class to solve a particular problem. I think that it would be great indeed if Crunchy could be made available from the web in a secure way. Hopefully, by the time we make the 1.0 release, Crunchy will have been found to be useful enough that someone with the appropriate resources will make this happen. André
