These two test cases are basically the change in a nutshell.

There is no benefit of using _s here, but it also does no harm. Generates exactly the same code, I believe. I suppose the rules for when ASCIILiteral is helpful are too confusing.

This one-liner is more efficient than two append calls.

    extension = makeString(extension, '-', lowercase);

This one was Yusuke's suggestion. :)

Oh, that's good to know. I wasn't sure whether `foo = makeString(foo, ...)` was a good pattern or not. Will update.
