    Probably a good idea. The manual does say that the `pushed' field is
    manipulated by the main routine but a specific "hands off" warning
    might be appropriate. It might also be a good idea to add some
    comments in the `forms.h' file, as well, just to keep people from
    wasting their time chasing up a blind alley.

    Personally, while it is far from my place to criticize any of the
    design decisions made in XForms (TC has done an admirable job -- I
    stand in awe of a truly great hacker of the first order), I would
    probably have made most, if not all, of the XForms data structures
    opaque and used function calls for any necessary application access of
    structure members. It's far too late to do that now, of course, since
    it would break a huge amount of code.
