[Richard Suchenwirth] 2006-02-15 - "Hot patch" is in my understanding a technology where you can modify software while it's loaded in memory. In old BASIC days, one would POKE a byte into an address, and hopefully get the desired effect :-) In [Tcl], the most straightforward way is to redefine a [proc] so that in addition to its old body, it gets the changes as wanted. Examples on this Wiki:
   * [Let unknown know]
   * [Alternative dialogs for pocketPC/etcl]

[Overloading widgets] might also fall into this category...
