  # Two runtime dependencies and no more. `predicator` evaluates the

  # this package consumes that family from a host application, not from its
  # own core, and a runtime dependency added to this list is a decision to
  # record, not a convenience to reach for. `solid` pulls `date_time_parser`
  # and `decimal` transitively; they appear under it in `mix deps.tree` and
