While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
Fix#3369. The parser had failed to account for `TRUE` and `FALSE` when supplied as arguments to a function.
I had hoped to be able to do something about its inability to handle defined names as well. I failed. I think another section might need to be added to the Writer output which specifies the defined names. I haven't yet located any suitable documentation.
