If we were to study software now in the way Richard Helm, Erich Gamma et al. did in the early 1990s would we find Proxy, Façade, Builder, etc. of course we would since the feedback loop of people knowing about them causes them to use them. So we now have a self-fulfilling prophesy, and a design loop it is impossible to escape from. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:[email protected] 41 Buckmaster Road m: +44 7770 465 077 xmpp: [email protected] London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
