Probably because at one point lists didn't even have the index() method, 
and when it was suggested and (I believe) Raymond H. added it, I suspect 
nobody also suggested that implementing find() was a good idea so it 
wasn't done.

And, given both that index() exists and the recent discussion about the 
potential problems caused by find() returning a valid slice index when 
it fails, maybe it's _not_ a good idea...
