def fetch(key)
  # @note
  #   Previously we used exceptional flow "hash.fetch(key) rescue hash.fetch(key.to_sym)".
  #   This flow can generate a lot of useless objects during rescuable `KeyError` exception
  #   (useless error messages, backtraces, etc, object that was silently suppressed).
  #   So, the "if"-#key?-oriented flow is better (generates fewer number of objects statistically)
  source.key?(key) ? source.fetch(key) : source.fetch(key.to_sym)
