Oh well.  I'm surprised by this.  Maybe marshal should be extended.

I thought a named function was just a variable whose value was a lambda:

  def square(x): return x*x

is the same as

  square = lambda x: x*x

Of course the syntax is different (you can't have control statements in
a lambda) but I'd have thought if you can't marshal a lambda, you also
can't marshal a named function.
