Feature Request: nameof(::Enum)

[Ellipse0934]

When I define an Enum. Say @enum Fruit apple=15 banana=27. Given the value I would like to get the name of the the enumerated type. One way to get this is.

julia> Base.Enums.namemap(Fruit)
Dict{Int32, Symbol} with 2 entries:
  5  => :apple
  19 => :banana

It would be convenient to have a method dedicated to this. I think nameof is suitable here. The resultant behaviour being
nameof(Fruit(5)) == :apple

I'm happy to implement it if this makes sense.

You can already use Symbol(Fruit(5)) for this. Could perhaps be documented better.
