Hmm, good point.  I'd hate to make the SRFI more bulky, however.
What do others think?

Why?  The cost is negligible, the benefits substantial, and the
alternative you propose is way baroque.

Olin>      <script prelude> -->

Olin>    Is that better?

Yes, good point.

Olin>    Also, I'd suggest making the terminator be newline-bang-sharp, not

I don't see a great likelihood for a false positive.

Olin> 5. The draft says

Olin>    Err... are you *sure* you want to do that?

Yes.  If I'm not mistaken, scsh behaves in the exact same way.

Olin>    Invariably, a relative pathname in Unix means relative to the

Olin>    surprises...

No, I'm changing that for the *configuration* *describing* the Scheme
script.

Olin>    This is problematic for other reasons, as well. What if I
Olin>    want to load stuff in from some standard library directory,
Olin>    regardless of where you might locate my script?  Are you
Olin>    disallowing absolute pathnames?

No, I'll be more explicit about that.

Olin>    If you really want to do this relative-to-the-script pathname
Olin>    resolution, you might be better off saying that *relative*
Olin>    pathnames are interpreted this way, and absolute pathnames

OK.
