          Issue ID: 18735
           Summary: all versions of find and canfind should identify usage
                    of predicate
           Product: D
           Version: D2

          Severity: enhancement
          Priority: P1

In the first overload of find, it says:

Elements of haystack are compared with needle by using predicate pred with
pred(haystack.front, needle)

This same description should be repeated in all flavors. It can be important
when giving a custom predicate where the two parameters are not the same type.
