Enum name convention consistency

[Sam Hu]

>From std.range:
enum StoppingPolicy
{
    /// Stop when the shortest range is exhausted
    shortest,
    /// Stop when the longest range is exhausted
    longest,
    /// Require that all ranges are equal
    requireSameLength,
}

enum State; 
A fiber may occupy one of three states: HOLD, EXEC, and TERM. The HOLD state 
applies to any fiber that is suspended and ready to be called. The EXEC state 
will be set for any fiber that is currently executing. And the TERM state is 
set when a fiber terminates. Once a fiber terminates, it must be reset before 
it may be called again. 

HOLD

EXEC

TERM

>From std.stream:
enum FileMode {
  In = 1,
  Out = 2,
  OutNew = 6, // includes FileMode.Out
  Append = 10 // includes FileMode.Out
}

Would not this be better if we keep the name convention consistent.
