Looks interesting, covariance (upcasting) is definitely a feature
requirement for an standard rc library.
The delegates are interesting. A bit brittle, guess we need some
compiler supported lowering to make non-GC allocated delegates cleaner.
You could try sth. along the lines of
delegate!(sum, "(int v) => sum += v")
but that needs a mixin to rebind the lambda's context.
