Consider these tests as suggestions for what a standard library for
your language could contain. Each test function tests the implementation
of one stdlib function.
Put the implementation in the file `stdlib.diy` at the root directory
of the repository. The first function, `not` is already defined for you.
It's your job to create the rest, or perhaps something completely different?
Anything you put in `stdlib.diy` is also available from the REPL, so feel
free to test things out there.

PS: Note that in these tests, `interpret` is used. In addition to parsing
and evaluating, it "unparses" the result, hence strings such as "#t" as the
expected result instead of `True`.
