    A transaction (or maybe transaction handle would be the better term) is available from reevaluation and admission tickets.

    A transaction (or maybe transaction handle would be the better term) is available from reevaluation and admission tickets. That is, everywhere during a transaction, you can read reactives, but also create them. The reading values is core to any reactive propagation. But creating reactives using the Initializer is a liability to the scheduler, but a superpower to the operators. Its a classical tradeoff, but it would be better to not make this choice by default, that is, reactive creation should be limited such that we can experiment with schedulers that do not have this liability.

    In case you wondered why everything in REScala is in these weird bundle traits, this is why.

    In case you wondered why everything in REScala is in these weird bundle traits, this is why. The ReSource below depends on some abstract state, which is defined by the concrete scheduler implementations. As basically everything else references ReSources, everything must be bundled together. This is good for users, because they get strong guarantees about the used correctness, and the API is still OK. Its terrible for us, because the Scala Incremental compiler does not really work anymore.
