Resetting a memoized function

I know that clearCache will clear the cache of a MemoizedFunction, but how would you reset its other properties to their defaults? I would have thought that rebuilding it with memoize() would do so, but the test below shows that that does not work.

mf=memoize(@localFcn)  %default property values

mf = 
  MemoizedFunction with properties:

     Function: @localFcn
      Enabled: 1
    CacheSize: 10

mf.CacheSize=3; mf.Enabled=false   %make some non-default property settings

mf = 
  MemoizedFunction with properties:

     Function: @localFcn
      Enabled: 0
    CacheSize: 3

clear mf
mf=memoize(@localFcn)  %clear and rebuild -- but property values do not reset!!!!

mf = 
  MemoizedFunction with properties:

     Function: @localFcn
      Enabled: 0
    CacheSize: 3

function y=localFcn(x)
  y=x.^2;
end

According to +matlab/+lang/MemoizedFunction.m

% 2. MemoizedFunction objects are persistent to a session of MATLAB.

% For Example:

% f = memoize(@plus);

% f.Enabled = 0; % By default, Enabled == true

% clear f; % Only clears the object f.

% h = memoize(@plus);

% isequal( h.Enabled, false ); % State that was set by 'f'

So this is by design.
