2.48491 SL2=: 13 :'x+&^.y' 3 SL2 4 2.48491 Tacit versions that are identical: SL ([: ^. [) + [: ^. ] SL2 +&^. Maybe it would be useful for J to have a "beginner tacit" and an "advanced tacit". t1=:([: ^. [) + [: ^. ] t2=:+&^. Would it then be possible for J to translate: t1 into t2 t2 into t1 It might make learning both easier.
