If this is that unusual, I am really wrong about SPARK indeed. On the  =

other hand, look at the SPARK introduction at WikiPedia, it talks about =
 =

check/assert annotations, no where it talks about user rules. The SPARK =
 =

LRM talks about annotations, no of very few about user rules. Whenever y=
ou  =

see an introduction about SPARK, it is said to be an Ada subset with  =

annotations. And indeed, notations are there.

Do you see the point ?

May there are two very different way to work with SPARK so. This will no=
t  =

ease things...

Would be difficult to explain (and to me to) that what is so much focuse=
d  =

on, just appears in very cases. So why annotations and so much spots on =
it  =

?
