- At the risk of repeating parts of my recent postings and Bertrand Meyer's reply:
-
- Yes, it can be performed statically.
- ISE's first release of 3.0 doesn't do it, but it is `at the top of the list'
- for the second release.
-
- The algorithm in Chapter 22 seems very straightforward, I guess ISE's estimate
- of two months to implement it comes from wanting to mnake it fast and/or
- incremental.
-
- The first release of Eiffel/S on Pc did the checks dynamically. I think there's
- a second release now but only SiG can tell you more.
-
- Mike.
