Sorry, some Turbo Pascal-isms in my initial mail -- I see that
FreePascal's TCollection class has an explicit .Sort method so this
helps me re-sort on demand, but it doesn't help me switch the Compare
method. So, my question still stands.

Unless I'm missing something, TSortedCollection lacks the ability to
change the Compare method after initialization and/or explicitly re-sort
the collection on-demand. I was planning on handling each new (re)sort by:
1. Initializing a new TSortedCollection with the desired Compare method
2. Copying the contents from the old collection to the new one
3. Swap collection pointers; destroy the old collection.
This works without much penalty because the collection will never get
beyond a reasonable size, but the implementation makes me cringe. Is
there a more elegant way to do this (without writing my own sort
routines for a plain TCollection)?
