The only thing I can think of off the top of my head is to write a
hinted-array macro that turns (hinted-array Class expr) into ^Class
(into-array Class expr). Emitting type hints or other form metadata in
macros is do-able, but sometimes a bit tricky. Something like this might
work (untested):
(defmacro hinted-array [class expr]
(with-meta
`(into-array ~class ~expr)
{:tag class}))
