Building a long list with 'range' just to apply it (e.g. to 'circ') is rather
inefficient.
In this case, I would recommend 'fifo' to build large circular structures:
(let L NIL
(for I 200000
(fifo 'L I) )
...
The result is a little different though:
: (let L NIL (for I 7 (fifo 'L I)) L)
-> (7 1 2 3 4 5 6 .)
Depends on the use case.
