it would be more or less trivial to make a macro that switches between non
promoting + primitive loop and promoting and boxed loop:
(defmacro fast [body]
`(let [+# +, *# *, -# -, loop# loop ...]
(binding [+ +', * *', - -', loop loop' ...
+' +#, *' *#,-' +#, loop' loop# ...]
~...@body)))
;; NOT TESTED! Just a brainstorming
And of cause it would just work the same when the defaults were the other way
round only would need to rename fast to safe or just-working or whatever is
fitting.
It does not has to be part of c.core or c.contrib if Rich does not like it but
it might very well be in every code if someone likes it for their little realm
as I would.
