So we could, although I think the current C-based version does well
enough.  My main ambition is not to compete with the Q interpreter,
but to make the power of generalized term rewriting readily available
to Scheme programmers.  For that they need an appropriately Schemish
and S-expression-based interface.

The next release will provide those things, but will not have numeric
tower support or list memoization; when you pass a list to Q and Q
returns a syntactically equal list, it will be only semantically equal
(equal and not eq) on the Scheme side.

Thanks, fixed.  On most systems you should only need to say -lqint anyhow.
I spotted another typo in the Q manual in at least two places: "quadrupel"
should be "quadruple".
