It is definitely fair to say that. We claim extenuating circumstances, however, since many of the glitches are due to X Windows (11.1). In fact, in the process of porting to X 11 release 3, a number of cases were uncovered in which the Eiffel classes had to be corrected because they were programmed around X 11.1 bugs which (fortunately) were fixed in the 11.3. This does not exonerate us totally (some of the glitches are definitely our responsibility), but anyone who has worked extensively with X, especially pre-11.3, will agree that this is not the best possible piece of software to use as a basis for development. Release 2.2 of Eiffel is based on X 11.3 and all the glitches mentioned should have disappeared. A number of improvements will also be included, in particular with respect to speed (menu display was too slow) and the possibility of having arbitrary client workstations. Also, the GOOD utility will work much more nicely. > Although Eiffel allows calls to external C routines, only basic C type > parameters can be passed between C and Eiffel. [...
