Bojan, thanks for the examples! This is nice to know that many things from C# work in the interpreter. However, these are not the kinds of complications to show to introductory students. If there is a way to turn on classes and functions in the compiler, that would be perfect, and could have an impact in the classroom. -Doug > > _______________________________________________ > Mono-list maillist - [email protected] > http://lists.ximian.com/mailman/listinfo/mono-list > _______________________________________________ Mono-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-list
