I understand that your proposal *only* makes it the default, but I think it would be more elegant to have the default extracted from the code and visible to the user so as to allow for her to over-ride the default by resetting the value.

Can you tell why you think that defconst is more elegant than a
hard-coded default?  I think they are basically the same.
