(1) What is dataset? Are we passing it a lambda? OK, so semi-colons are optional. Hmmm... Apparently we have a list of emp constructors. Is this correct? (2) How is it that the "{}" are constructing a list of emps? Why is there no code like "[ emp empno:7369, ename:'SMITH', job:'CLERK' emp empno:7499, ename:'ALLEN', job:'SALESMAN' emp empno:7521, ename:'WARD', job:'SALESMAN'] as List"? (3) And what about emp? Who defines the class emp and its constructor? Where? (4) And what is this business with the grape.grab inside the static {}? I've never seen the keyword static in groovy code before. Why static? Why not "@Grab" instead of grapes.grab (inside the static)? Thanks siegfried
