This PR has three parts:

  • Lazy-loading Segments instead of eagerly in constructor
  • Caching segments for candidates, by wrapping them as a MemberPath
  • Use type check as fail-fast in IsSameAs

It triggered me that:

  • the candidate memberpath was segmentized 1-3 times in IncludeMemberByPathSelectionRule, while we can do with atmost 1
  • segments were eagerly computed, where I prefer to minimize the work in the constructor
  • the segments were (to me) unnecessarily copied into a List.
  • the candidate memberpath was segmentized before the declaringTypes are compared.

I think IncludeMemberByPathSelectionRule becomes prettier
