You and Eli have convinced at least me, with the following caveat:  I am 
wondering if anyone would object to

  - keeping "find" as is, but
  - raising an error if the returned element would have been #f.

This seems to attain the best of both worlds by keeping the convenience and 
avoiding the inaccuracy and fragility.
