That implies that you can easily change all the references to it.  In
this particular case, I don't feel like munging the insides of TCL,
nor would I wish to maintain said hacks even if it were relatively
easy.. :-)

There are some genuine situations where one would really just like
to associate a little extra data with a FILE*, and I think that making
some very small provisions for it is not that out of line.
