Yes probably true, that's just an optimization though, and it's easiest
to follow a straightforward approach first.  If there's a GC you might
as well use it, especially for stuff like the reader (Lisp terminology
for the thing that parses S-expressions).  Your Lisp isn't going to
spend much of its time doing that.

Would that also handle trailing parens (foo (bar (.... baz))) instead of
treating "baz)))" as a Forth word?

I'm not sure what you mean by that: traditionally you'd use cons nodes
that each hold two values.

I wouldn't try to use the Forth text interpreter directly as a Lisp
reader.  You start wanting read macros written in Lisp, etc.  Assuming
the target machine is a PC or comparable, I wouldn't worry about the
efficiency of the reader.  I doubt you're planning to run megabytes of
Lisp code.

Nice.  It occurs to me given your interest in Euler problems, that your
Lisp should also have bignums.
