How would your method get overwritten anyway?  (I know it's possible, so in
some sense it's a rhetorical question, but by answering it we can discuss some
design philosophies.)

I have some sympathy for your concern, but I have learned to adopt the
following attitudes:
 - if other people overwrite my method, that's their business; the
   warranty is void
 - if I overwrite my own method *accidentally*, I either have a messy
   design, a bad approach, or a small brain :)
