> If you know the concepts behind these, you can quickly grok any other programming language.

"Grokking" a programming languages is just a means to an end, and far from being the most important means (well, for interesting problems, at least). Most (though not all) of important concepts in CS have absolutely nothing to do with the choice of language.

At my university they taught Scheme (SICP) in Intro to Comp Sci, and C -- both in the first year -- and all the rest was just data structures, algorithms, computational complexity, operating systems, numerical algebra, compilation, and electives in vision/graphics/PLs/DSP/whatever. We could do the exercises in whatever language we chose (usually C). In short they taught us just theory and one practical PL (maybe Java, too, for concurrency problems) so that we could actually do the exercises, and boy did we have a lot of good programmers who came out of that school. I owe to my university the realization that the programming language is one of the least important things in CS and software engineering.
