All an output range is is a type with a 'put' method. That's it. You're
making it out to be far more complex than it is.
Directly from the docs:
(http://dlang.org/phobos/std_range.html#isOutputRange)
void myprint(in char[] s) { }
static assert(isOutputRange!(typeof(&myprint), char));
No 'put' in sight, except as a substring of isOutputRange.
I don't think you realize what a beast supporting all output ranges is,
or using them (hint: calling r.put for a generic output range is an ERROR).
