/// Tests for rules shared between various speech styles:
/// *  modified var
use crate::common::*;

// The basic layout of the tests is:
// 1. Sweep through all the SI prefixes
// 2. Sweep through each group of SI units
//    a) with both singular and plural without prefixes
//    b) with both singular and plural with one prefix
// 3. Sweep through each group of units that don't take SI prefixes
// These are broken into chunks so it is easier to see errors, when there are errors
