Can someone explain to me why map() is not equivalent to foreach in the code above? From what I can tell, map() doesn't do anything at all on objs, even though it is a perfectly legitimate range (as far as I can tell).
map() constructs a range that invokes a given function on the source range if an element is requested – but only then. In other words, map is fully lazy. David
