Can't `with-open` about clojuredart

[valerauko]

I ended up "writing" my own with-open, but then I soon realized that half the things I wanted to with-open were actually closed with .cancel and not .close. And then some more had to be .dispose'd...

And creating a closable protocol would require lots of tactical extensions.
I suspect that with-open must stay true to its original spirit of relying on conventions and not interfaces.
Something like?

(with-open [controller (xxx) :close .dispose] ...)
