Except that print is not a void context.

I think you might be misunderstanding. blahblah wasn't talking about the call to print. He was talking about the call to map ("map in a void context"). And the call to map is in a void context - its return value doesn't go anywhere. But as he also pointed out, that's no longer a problem. Or, at least, it's not a problem from a technical point of view. I'd still argue that it's not the clearest way to write the code.
