No, please don't do that. It's put(outputRange, data);


Why?

import std.range;

struct ORange
{
    void put(char) {}
}

static assert(isOutputRange!(ORange, char));

void main()
{
    char[] buf = "hello".dup;
    ORange r;
    //r.put(buf); // fails
    put(r, buf); // works
}

I have said before, making the UFCS function the same name as the member 
hook it uses was a bad anti-pattern. Now, you must always use the 
non-UFCS version of put, which sucks.
