Pardon if this is a stupid question, but...

Is there a way to redefine car such that it behaves as normal given a normal
list, and does a force on its return value if passed a stream?  Along the
same lines, has anyone out there implemented a functional (i.e. stream) I/O
package of any sort for Scheme?  Being an FP snob, I hate to use side-
effecting I/O, but the first question seems to be a prerequisite for the
second...

Thanks in advance,

Joe
