+  ShiftExpression : ShiftExpression << AdditiveExpression
+
+  1. Let lref be the result of evaluating ShiftExpression.
+  2. Let lval be ? GetValue(lref).
+  3. Let rref be the result of evaluating AdditiveExpression.
+  4. Let rval be ? GetValue(rref).
+  5. Let lnum be ? ToNumeric(lval).
+  6. Let rnum be ? ToNumeric(rval).
+  7. If Type(lnum) does not equal Type(rnum), throw a TypeError exception.
+  8. Let T be Type(lnum).
+  9. Return T::leftShift(lnum, rnum).
