Programming languages, continued

Following up on this post...

Nobody in Monday's or Wednesday's class complained at all about doing the assignment in Scheme. In fact, they've finally buckled down to actually work on the problem, which was due two weeks ago. (This course isn't a prerequisite for anything else, so I can let deadlines slide if necessary to make sure everybody actually "gets it".)

I've put the lectures and new material on hold, and have been mostly just helping students get their programs working. One team realized, by the time they had passed one particular tricky test case, that they had used three higher-order functions in four lines; doing the same thing in Java or C++ would have been probably fifty lines of code.
