This. As far as I'm concerned, the standard libraries are
nearly useless without a standard way to invoke reliance
on them. There is no using libraries in portable code if
invoking libraries is not portable to every implementation,
nor if it requires invoking them by different names.
I don't think anybody cares too deeply what name we use;
but we care deeply that there should be a known, portable
name. It's rather like passing a law that says drive on
the left/right side of the road; either way works, but the
law must be passed anyway because it's something that the
drivers must agree on and it affects the design of the
vehicles' control interface.
