I think one reason it was originally implemented is because the '+'
operator could potentially be overridden and there needed to be a way
to concat strings.

So, when you see

 x = "foo" + "bar"

do you think of the '+' as a given for a string concatenation operator or as:

x = "foo".+("bar")

where, someone could have changed String#+.
