What to use instead of array.join if RHS is not a range?

But it doesn't. It requires a range of ranges, and a string is a range of 
dchar. You need a range of strings to use join on strings.

assert(join(["hello", "silly", "world"], " ") == "hello silly world");

will work.

assert(join("hello world", " ") == "h e l l o w o r l d");

won't. You seem to be looking for a function which will insert an element 
between every element in a range rather than one that joins ranges, and I'm 
not aware of any function in Phobos which will do that. There may be a way to 
get one to do what you want, but I can't think of how at the moment.
