  # String#-@ on Ruby 2.6 will dedupe a frozen non-literal String. Ruby
  # 2.5 will just return frozen strings.
  #
  # The pooled implementation can't tell the difference between frozen
  # literals and frozen non-literals, so must always return frozen String
  # instances to avoid doing unncessary work when loading format 2
  # TZInfo::Data modules.
  #
  # For compatibility with the pooled implementation, just return frozen
  # string instances (acting like Ruby 2.5).
