--------------------------------------------------------------
For dynamic groovy, it's much harder to implement such a feature, as its type
info is detected at runtime. So we need generate much more complicated bytecode
to pass the condition expression to the expression in case statement, in the
meanwhile, the condition expression can not be evaluated multi-times to avoid
side effect, i.e. we should save the evaluated result first...
P.S. Using {{@TypeChecked}} will take effect too.
