Not that I know of. Called macros above are let-print; called functions are
cons, map, factor-term, rest, make-product*, concat, and
subexpressions-of-product. All are called by both versions; cons, map, rest,
and concat are the clojure.core versions and let-print is just
(defmacro let-print [bindings & body]
`(let ~bindings ~@(map (fn [x#] `(println ~x#))
(take-nth 2 bindings)) ~...@body))
which I find handy sometimes when debugging, because I can just slap a
"-print" at the end of a let to add some debugging dumps to the console
output. (I also have eval-print and intend to add loop-print to dump loop
variables every time around the loop.)
I had been debugging the above function, which work led to the change that
triggered the new problem. Interestingly, changing the "let-print" back to
"let" alters the error message, specifically, the cryptic number after
"unknown constant tag", but has no other effect.
The functions factor-term, make-product*, and subexpressions-of-product have
all been working for ages, and have not changed recently. None type-hints
anything, return value or otherwise.
