Ah, ok. That answers another question I had which was why you added a run keyword at all when it was so repetitive! I'd left out the run keyword before, but was confronted with the LISP output - which I assumed was something like an "explain plan" on a database, and I didn't read the stack dump closely enough.

Another issue: I wanted to see the output of just range. So I typed in `8 range` and got no output. Then I looked through the examples for something simple that might output a list. I tried the primes example, `100 range-from-1 rest (gcd 1 neq) uniq-by` but got blank output. Thoughts?
