Title
Body
I have some Java code that uses curly braces in two ways // Curly braces attached to an 'if' statement: if(node.getId() != null) { node.getId().apply(this); } // Curly braces by themselves: { List<PExp> copy = new ArrayList<PExp>(node.getArgs()); for(PExp e : copy) { e.apply(this); } } outAMethodExp(node); What do those stand-alone curly braces after the first if statement mean?
