Input Parser and Enumerations

Can anyone help me with why this might not work?

 classdef WhichIlsop
    enumeration
        Prod()
        Test()
    end    
end

Then when this enum is passed into a function with parameter name ilsop, I want to validate the inputs.

p = inputParser;
  p.KeepUnmatched = true;
      p.FunctionName = 'bah';
      addRequired(p, 'ilsop',  @(x) isa(x, 'WhichIlsop'));
      p.parse(varargin{:});

I get this message when evaluating the 'parse' line. The other lines are the diagnostics I've done below.

 The value of 'ilsop' is invalid. It must satisfy the function: @(x)isa(x,'WhichIlsop'). 

>> class(ilsop)
ans =
  'WhichIlsop'
>> isa(ilsop, 'WhichIlsop')
ans =
logical

Bah ... p.parse(ilsop, varargin{:});
