See, e.g., <a href="http://wiki.portal.chalmers.se/agda/agda.php?n=Main.TypesSummerSchool2007" rel="nofollow">these notes</a>.</p> Thanks to sfvisser and Elliott Hird who pointed out that my BNat type corresponds to the Fin type from Agda (though without full dependent types and with a less convenient notation).

The nice thing about Agda is of course the numeric syntactic sugar, allowing you to write actual numbers at the type level.
