You can already. 


To go from enum value to string just use the 

to_string () method:

enum Test {
ONE,
TWO
}

void main () {
var a = Test.ONE;
print( "to_string() method: " + a.to_string() + "\n" );
print( "as %%s, but still needs to_string() method: %s\n", a.to_string() );
print( @"as template: $a\n" );
}

To go from string to enum value, first instantiate
your enum as an EnumClass then use the get_value_by_name ()
method. Similar to using the n_values field:

enum Test {
ONE,
TWO
}

void main() {
var a = (EnumClass)typeof (Test).class_ref ();
EnumValue? value = a.get_value_by_name ("TEST_ONE");
if (value != null) {
print ("%i\n", value.value);
}
}
