Hmm. If you remove 'actions, how about also trying to use just a single 'cons cell:

  (iflet (parsed . remaining) (parse parser remaining)
    ...)

  (def return (parsed remaining)
    (cons parsed remaining))
?

If the speed increase is that large on that testbench, it might very well be due to garbage collection.

This might be an interesting page for our problem here ^^

Tried changing the list to a single cons cell. I did not see any additional performance boost.
