I don't follow. CSP scales very well and Go implements CSP.

Go has no shared access, thread safe map and no-one has created one that is in the standard library. Of course Java is a shared-memory multithreading language whereas Go is a CSP one, so the idea of a shared access memory safe data structure is actually anathema. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
