i agree that the case of -b is extreme, but your response is still unfair to the original problem. people that jump from bridges usually do that intentionally. the intention of the user who complained about his code (below) was certainly not to jump off a bridge, but to walk over it. and yet he's fallen into cold water. a bridge which makes you fall when you want to walk and not to jump has flawed design and is a good candidate for abolishing.

testfunc = function(data, group) print(names(subset(data, select=group)))
