The Perfekt theory of M-ideals

We revisit some ideas of K.-M.~Perfekt who has provided an elegant
framework to detect the biduality between function or sequence spaces
defined in terms of some o-resp.\ O-condition. We present new proofs
under somewhat weaker assumptions than before and apply the result to
Lipschitz spaces.
