Those with Enrich Platinum/Oneworld Emerald, if flying (any class) with a Oneworld airline, have access to a "First Class" Lounge. Not every airline have First Class lounges, but those who does, it can be very good.

I went to Melbourne Qantas First Class Lounge flying Y with MH using my Enrich Platinum status (by default, MH will direct you to a rather lousy Marhaba Lounge). It is one class above MH's own First Class Lounge at KLIA, and 3 classes over the CC access lounges like PPL or Marhaba. Table service ala-cart menu, with very good choices freshly cooked on site. Extensive wine list.

They also have a First Lounge in Changi, so if you are flying MH to KUL, can also use that lounge, if your flight timing fits (Changi lounge restricted hours based on the 380s evening schedule.)
