 find_first would be a performance enhancement.  The current alternative
 would be something like:

 argmax (some boolean function...)

 which requires a lot of extra work if all you want is the index of the
 first occurance.

 This is frequently wanted for 1-d arrays, where it's meaning is
 unambiguous.  I think semantics for n-d (n > 1) arrays is up for
 discussion.
