There's a case for the Wolfram Programming Language since instead of having a standard library...or any libraries at all...the language itself incorporates all the extensions [some 5000 functions].

If nothing else, this is a language design that challenges the way people think about programming languages. What I find interesting and worth investigating is the possibility that not having to import this and that from a somewhat arbitrary taxonomy of siloed knowledge may reduce cognitive overhead. So it's on my list of languages to investigate over the next few months.

YMMV.
