The latter. For example, you need to be able to take an arbitrary
string and use those builtins to select a part of it. Currently
you can't do it, since the resulting string isn't quoted, and is
rescanned so the quotes are lost.
Also, there needs to be a mechanism for handling arbitrary strings,
including strings with unbalanced quotes. This is a continual problem
with Autoconf; it causes lots of problems with users.
