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}))

Sorry, full of questions about type hinting at the moment.
I've found myself writing a lot of expressions like this:
^[Lorg.semanticweb.owlapi.model.OWLClassExpression;
(into-array OWLClassExpression
[(ensure-class o name)
(ensure-class o disjoint)])
Now the strange thing here is that I have to type hint an expression
which clojure clearly knows the return type of (although only for the
expression and not for the function).
This is particularly painful because I'm only constructing the array to
call a variadic method in Java, and the type hint is particularly
verbose.
Is there an easier way?
