Well, at least Haskell is probably better as an introductory language
than Lisp or Scheme.  But what schools actually do this?  My
perception is that the vast majority of schools use C++ or C# or Java,
typically relegating functional programming to a single second- or
third-year course.  Of course it's well known that MIT used to use
Scheme, but they switched to Python a couple years ago.

I don't think a single language is necessarily going to be best for
all students.  If a math major comes to you wanting to learn some
programming for theorem-proving, bearing in mind that they probably
aren't interested in learning more than a single language, would you
try to start them out with Python, or would you just give them the
functional language that they're ultimately going to want?
