[TCLCORE] WITHDRAWN: TIP 5

[Eric M. <er...@aj...>]

Some good points were made today about TIP 5, and so I have decided to
withdraw my proposal in favor of a new proposal, TIP 6, which should show
up here soon.  TIP 5 has been marked with "Status: Withdrawn" and
"Obsoleted-By: 6" per the TIP header format.

The reasons for withdrawal are:

   1.  It adds too much complexity, in particular with respect to
       memory management.
   2.  It is not "type safe" with respect to the function signatures
       of callback functions; in particular, the API
       Tk_SetWindowCallback(...) requires the casting of the function
       pointer to a "lowest common denominator" pointer (basically,
       (void *)), which defeats the ability of the compiler to catch
       type mismatches between a (TkCreateProc *) and the function to
       be used as a TkCreateProc.

Thanks,
