I think what we want to do is add more methods to Value, and in
particular a way to call inferior functions.  So, the above could be
something like:

    self.val.call_method('str')

There are probably some other holes in Value.


We also want a way to create expressions, though so far I think this
is mostly useful for a new language implementation, which isn't on my
near-term to-do list.  One fun idea here is that we can give
Expression the same API as Value.  Then you can write generic code
that either directly computes a value, or that creates the expression
to compute the value, depending on what you pass it.  Or is that too
wacky?
