First, I'll point out that standard Scheme doesn't have the concept
of the "result" of a file.  For example, the 'load' function doesn't
return a defined value.  A reason is that a module may contain a
*sequence* of one-or-more declarations and expressions.

I would look at the various 'eval' methods in gnu.expr.Language.
Some of these take an input file (a Reader or InPort).  The tricky
part is getting the result back.  The resulting values are written
to a Writer (which is presumably not what you want) or a Consumer.

I'd create an instance of gnu.mapping.Values to old the result.
That class implements Consumer, so you can pass it to eval.
Then after eval finishes, you can extract the results from the Values
object.
