--------------------------------------------------------------
The patch I submitted generates a hash called VALUE_MAP that maps values back
to their names (as strings) in ruby enums. It also includes a test for the
added functionality.

> Thrift enums are compiled into Ruby modules as Ruby has no native enum type.
> This works well except that without maintaining a separate map somewhere else
> or using reflection, it is impossible to get the names of the values back out
> from the values themselves. Essentially with this setup:
> module MyModule
> DATAPOINT = 1
> OTHERDATA = 2
> end
> If I have 2, it is very difficult to get "OTHERDATA" back out. It would be
> easier if thrift generated a static map from constant value to constant name.
> I am going to try and work on a patch for this.
