Typically, IMO with golf problems, solutions should be considered as being one one line of code (no CRs). CRs that are added when solutions are presented should only be used to improve the presentation of the code, but should not be used to lose a stroke. Thus, japhy's suggestion of adding a CR between a variable and a following function name is violating the rules (as this trick can help reduce the number of strokes in previous golf challenges). In other words, the code should work if one was to do s/\n\\g;
on the golf code.
