This isn't necessarily bad, but I observe that it would be difficult or
impossible to add fortnight support to intervals as an extension rather
than by modifying the scanner tables that the interval parser uses at
original compile time. You might be able to override symbols with a C
extension, but parts of the parser are static (in the C sense), so you'd
need to override and duplicate a lot of the existing functions. Of
course, a hookable interval parser is absurd in the first place.
