It has just been tweeted that Martin Odersky has just added Dynamic into trunk. Apparently, this is HUGE. Why?

Cheers - it didn't come up in my search. SO search is SO rubbish — oxbow_lakes, Jan 17 '11 at 15:48

Dynamic adds developer driven dynamic binding (dynamic dispatch) and gives a subset of the features of dynamic typing to Scala.

See this pastie from Jorge Ortiz:

Get the illusion of static typing with none of the unsettling and unhappy development woes – oxbow_lakes Jan 17 '11 at 15:48

You mean dynamic typing right? Scala has always had dynamic binding. – sepp2k Jan 17 '11 at 17:21
Scala has never had dynamic binding. The JVM internally has dynamic binding. – Viktor Klang Jan 18 '11 at 10:06
Viktor, are you just being nit-picking or do you really think there is no dynamic binding in Scala (or the bytecode it compiles to, which is equivalent)? – Raphael Jan 19 '11 at 00:51
