/**
 * There was a bug in the old Lower that didn't fully propagate type information
 * by way of assignment. 'q' in the example below would have finished a double
 * even though it can get an object value through the assignment 'q = l' 
 * 
 * Furthermore, this caused type coercion to be done at q = l, and not a q = q * 2, 
 * which is a bug. This test ensures it happens in the correct order
 *
