It would be great if glib-mkenums had a "ValueName" susbtitution, so that from the following example:

typedef enum {
  PREFIX_THE_FIRST_VALUE = 1,
  PREFIX_ANOTHER_VALUE   = 2,
} PrefixTheXEnum;

We could get "TheFirstValue" and "AnotherValue".

It would be very handy to setup glib-mkenums to generate error type information with error domain registration in GDBus, something like:

GQuark
@enum_name@_quark (void)
{
    static volatile gsize quark_volatile = 0;
    static const GDBusErrorEntry @enum_name@_entries[] = {
        { @VALUENAME@, "org.project.Foo.Bar.Error.@ValueName@"},
    };

    g_dbus_error_register_error_domain ("@enum_name@_quark",
                                        &quark_volatile,
                                        @enum_name@_entries,
                                        G_N_ELEMENTS (@enum_name@_entries));
    return (GQuark) quark_volatile;
}

Note: this wouldn't be enough to get it useful for GDBusErrorEntry generations, as usually errors in DBus are given with the error domain, like "org.project.Foo.Bar.Error.Domain.@ValueName@", and the Domain part usually also comes from the enum name... that's another issue to handle.
