That doesn't work for a wide variety of possible cases, notably 
when `put` is a function template or when the code depends on 
std.range.put or some other UFCS `put` function. As such, it 
should be avoided in generic code, and then you might as well 
avoid it in general, lest your algorithm unnecessarily ends up 
breaking with output ranges you didn't test for after refactoring.

(Note that parantheses are not required in your example)
