Well as the worlds most heavy Smalleiffel/Smarteiffel user (i'm 0.74b
which is just in the middle) i can comment on one of this.

The speed of the SmartEiffel compiled programs is indeed excellent.

Code side is okay as long as you don't use inheritance a lot. Generics
and Inheriting from global cl***** (that only contains constants and
once routines) are okay. Heavy overriding methods does not work well
in general because of the lack of a VMT.

Look at the code generated output before you start and learn how it is
written.

But it is impossible to develop anything then toy programs with it
(and yes i consider the eiffel compiler itself as a toy project).

SmartEiffel is absolute unuseable for larger programs as compile time
is completely insane even on current 3 GHz Systems. compile_to_c was
about 2 minutes for a system (11 sec for SmallEiffel). Remember that
this is used even if you only change a comment.

SmallEiffel is simply too low developed to use it (no good runtime, no
working exception handling in debug mode, no multithreading, buggy
default garbage collector).

For me and many others the complete mistake was and still is
a) backward compatibility is not a goal
b) total ignorant development team
c) complete ignorance against multithreading (Hey thats what you
really can call stupid).

For EiffelStudio i can only say that i not liked the IDE. The library
is very unique and if you work once there is no way back. Speed is
suboptimal and ISE was not a nice company in the past.

I still like eiffel - even when i think most features were too much
hyped in the past (mostly multiple inheritance) - and i would really
like to see it survive. But to do it a new player must enter the arena
with a new product and this will not happen thanks to FOSS which
killed most alternatives in the software development world.
