Agreed. Until Java 8 I made the case for map/filter/reduce in Groovy, but never felt really upset by the collect/findAll/inject because of the Java symbiosis and the names didn't matter. Java symbiosis now indicated collect/findAll/inject is the wrong naming, and that map/filter/reduce is the right one. This militates in favour of change in GPars and in Apache Groovy. I guess this will now release the dogs of 'reduce vs. fold' war. :-) We should note that reduce and fold tend to have different semantics in the various functional languages and so this should be a non-debate it is possible to have all of reduce, fold, foldr, foldl, and not be confused (*). (*) Well except that I can never remember the efficiency rules for foldr and foldl so generally end up with the wrong one :-( -- 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
