Ok. What you need is a type hint in the interop call, so that the compiler
can emit a call to the right interface.
(.open #^SourceDataLine abstract-data-line-thingy 1)
If you had to do the several calls with that interface, you could the type
hint at a more central spot.
(let [abstract-data-line-thingy #^SourceDataLine (obtain-thingy)]
(doto abstract-data-line-thingy
(.open 1)
(.otherMethod 2)))
Hope that helps.
