# The type-digits package

This is a workaround until type-level literals (specifically
naturals) are more fully supported. The main difference is that these
types-level digits and numerals can be inspected/case-discriminated within
type family instances. See the `type-ord` and `type-cereal` packages for use
cases; they ultimately support the `yoko` package.
Arbitrary type-level digits, for when the radix itself doesn't
actually matter. It's currently base-128, because that seemed to best
expedite the compilation of the modules with which I using this
package. Please let me know what you find if you experiment with this.
`Type.Digits.radix` is the (arbitrary) radix. `Type.Digits.digit` computes
the `NameG` of a digit from its value (assuming its less than the
radix). Combinators are provided to compute a full type-level numeral from
values (potentially) larger than the radix.
The digits themselves all take less significant numeral as an argument. I
chose this over minimal digits in promoted lists because I wanted to keep the
actual encoding of type-level numeral smaller; they get quite large with some
of my uses and the type family computation becomes quite slow.
