+/// Regression test for dart2js that used to miscompile boolean and operations 
+/// if one of the operands was an int and the other was not (issue 22427).
+///
+/// Extended to all operations as there is a risk of similar bugs with other
+/// operators, e.g. `a % 2` _looks_ like it might be 0 or 1.
