Complex Algorithms

[darkfrog26]

It would be incredible if MetaRx could support even more complex algorithms with more advanced logic via Macros. For example, something like this:

val sub: Sub[Double] = Sub(0.0)
sub := subscribe {
  if (otherVar.get > 5.0) {
    otherVar + anotherVar
  } else {
    anotherVar
  }
}

The Macro would track all ReadChannel instances used within the block and update the resulting ReadChannel generated from the subscribe call. This would allow things like for-loops, conditionals, etc. to be used with simple logic, but become a ReadChannel that would fire events when any dependency changed.
