Description

Tang currently does not support Java enum in NamedParameter, i.e. one cannow write

public enum FooEnum { BAR, BAZ }

@NamedParameter(default_value = "BAR")
private final class FooParam implements Name<FooEnum> { }

We can fix Tang to invoke static .valueOf(String) method to instantiate enums from strings.
