  Summary

  The transformations that differ only by a level, each built at most once, so that
  an ordinary Simplify() allocates nothing to reach its transformation.
  

  Remarks

  Filled on demand rather than in the static initialiser, and it has to be. Building
  the factorisation entry reads RewriteRules, whose sets in turn build
  transformations of their own; doing that while this type is still initialising
  makes the two types depend on each other's initialisation, and one of them then
  reads the other's fields before they are set. Two threads arriving together may
  each build the same entry; the entries are equivalent and immutable, so whichever
  reference lands is the one everyone then uses.
