 > @RequestConverter(BobConverter.class)
 > public class MyService {
 >
 >     @Get("/general")
 >     @RequestConverter(CarolConverter.class)
 >     public HttpResponse general(Alice a, Bob b, Carol c) {
 >         // Try CarolConverter, AliceConverter and BobConverter in order, for converting each parameter.
 >     }
 >
 >     @Get("/special")
 >     public HttpResponse special(@RequestConverter(SuperAliceConverter.class) Alice a, Bob b) {
 >         // Try SuperAliceConverter, AliceConverter and BobConverter in order, for converting parameter 'a'.
 >         // Try AliceConverter and BobConverter in order, for converting parameter 'b'.
 >     }
 > }
