Further reduce imports of full
Prime.lean
. Here,Data.Nat.Factors
now imports onlyPrime/Defs
.For this, four lemmas had to be added to
Prime/Defs
fromPrime/Basic
. Many modules importData.Nat.Factors
, so their dependencies onPrime
theorems are now uncovered. Still, thischange will reduce the amount of what is imported, in general.
Motivation is a circular dependency that would prevent me from adding a lemma to
Prime/Basic
.
