-  1 //: Phase 2: Filter loaded recipes through an extensible list of 'transforms'.
-  2 //:
-  3 //:   The process of running Mu code:
-  4 //:     load -> transform -> run
-  5 //:
-  6 //: The hope is that this framework of transform tools will provide a
-  7 //: deconstructed alternative to conventional compilers.
-  8 //:
-  9 //: We're going to have many transforms in Mu, and getting their order right
- 10 //: (not the same as ordering of layers) is a well-known problem. Some tips:
- 11 //:   a) Design each layer to rely on as few previous layers as possible.
- 12 //:
- 13 //:   b) When positioning transforms, try to find the tightest constraint in
- 14 //:   each transform relative to previous layers.
- 15 //:
- 16 //:   c) Even so you'll periodically need to try adjusting each transform
- 17 //:   relative to those in previous layers to find a better arrangement.
