This introduces the `ArgsPacker` module and abstraction, to replace the exising `PackDomain`/`PackMutual` code. The motivation was that we now have more uses besides `Fix.lean` (`GuessLex` and `FunInd`), and the code was spread in various places. The goals are * consistent function naming withing the the `PSigma` handling, the `PSum` handling, and the combined interface * avoid taking a type apart just based on the `PSigma`/`PSum` nesting, to be robust in case the user happens to be using `PSigma`/`PSum` somewhere. Therefore, always pass an `arity` or `numFuncs` or `varNames` around. * keep all the `PSigma`/`PSum` encoding logic contained within one module (`ArgsPacker`), and keep that module independent of its users (so no `EqnInfos` visible here). * pick good variable names when matching on a packed argument * the unary function now is either called `fun1._unary` or `fun1._mutual`, never `fun1._unary._mutual`. This file has less heavy dependencies than `PackMutual` had, so build parallelism is improved as well. |
