No, I meant that, in my opinion, it is already clearly legal.
Or to be more precise about what I'm claiming to be legal:
- It's required that T must be EqualityComparable.
- I don't think it's required that the operator== that find()
uses must be the same one that's used when comparing
one T to another. (This is where I see a difference
between find() and lower_bound(). For lower_bound, the
algorithm requires a relationship between the comparison
used for sorting the list and the comparison used for
the earch.)
