That all sounds very reasonable.

Throwing an exception seems like a good default behavior since pretty 
much all of the other behaviors can be obtained from that using 
try/catch or checking for collisions before the insertion.  In addition, 
I know that my own uses of bimaps threw an exception when there were 
collisions.
