  # We aim to keep newest Idris commits buildable by as early of a
  # previous version as possible. In reality, we bump this regularly
  # to allow us to use new compiler/library features in the compiler
  # codebase, but an admirable longterm goal is to support building the
  # current version of the compiler with a previous version that is older
  # than its immediate predecessor.
