Eiffel Gotchas from 1997-8

Over on comp.lang.eiffel, Daniel Moisset was asking if anyone had a copy of the Eiffel Gotchas that were posted to usenet and on the web.
I wrote those gotchas, but they fell off the web when the ownership rules for .tm domains were changed (they had been on eiffel.tm).

I've now resurrected the old Eiffel Gotchas for interest and amusement - bear in mind that subsequent language and library changes will have affected many of these.
