new-function-parser-tests

While I was struggling to understand the details of function expressions
versus function decls, I typed a lot of test expressions into the REPL.
These two new tests contain enough to convince me that the parser is
correctly making the distinction (even if neither of the interpreters that
we test against seems to!)
