//: Phase 2: Filter loaded recipes through an extensible list of 'transforms'.
//:
//:   The process of running Mu code:
//:     load -> transform -> run
//:
//: The hope is that this framework of transform tools will provide a
//: deconstructed alternative to conventional compilers.
//:
//: We're going to have many transforms in Mu, and getting their order right
//: (not the same as ordering of layers) is a well-known problem. Some tips:
//:   a) Design each layer to rely on as few previous layers as possible.
//:
//:   b) When positioning transforms, try to find the tightest constraint in
//:   each transform relative to previous layers.
//:
//:   c) Even so you'll periodically need to try adjusting each transform
//:   relative to those in previous layers to find a better arrangement.
