The new parser is based on Java8, so it has to target to Groovy3. As far I know, there are some amazing features under development or test, e.g. MOP2, new Joint compiler, Macro(appears at the snapshot of 2.5.0), etc. Looking forward to them :)

Here again it would be no problem if it is recognized as Closure if that is more easy to accomplish. bye Jochen ------------------------------------------------------------------------ If you reply to this email, your message will be added to the discussion below: http://groovy.329449.n5.nabble.com/Lambda-expression-for-Groovy-3-tp5736169p5736171.html To unsubscribe from Lambda expression for Groovy 3, click here.
