Getting Field Names of a specific UDA in compile time.

[realhet via Digitalmars-d-learn]

Hi,

class Printer{
  @("NODES") int gem1, gem2, gem3, gem4, gem5, head1, head2, 
head3, head4;

  import std.traits, std.meta;
  alias Nodes = getSymbolsByUDA!(typeof(this), "NODES");
  enum NodeNames = ["gem1", "gem2", ....];
}

Is there a way to make an enum like the above with compile time 
programming?
I only managed to get the string[] by making a static foreach, 
but I don't know how to put that in an enum xxx = ...; statement.
