Tomek Walkuski a �crit :
> - what, in your opinion, is better in Ada, in contrast to Eiffel?

- a strong standard (Eiffel community is sadly split these days).

- string type system

- tasking

- distributed annex

- support for interfacing with hardware (e.g. representation clauses).

- not everything is a class (composability of Ada, packages, tagged
types, child packages...)

- more components and binding to common libraries

- bigger and more active community

> - what, in your opinion, is worse in Ada, in contrast to Eiffel?

- memory management (not GC - I know that there is nothing in the
standard that forbid it - and this would be certainly really handful for
some domain)

- multiple inheritance

- DbC with pre-condition/post-condition/invariant

I just like to add that I like very much Eiffel (I've done some projects
with this language) and to me it is second best after Ada. Worse
learning for sure!

Pascal.
