With due respect, I was just to say I don't agree with the critical  =

condition which appears in all wordings talking about SPARK. This (SPARK=
)  =

is just nice when you want to proof something works, when you want to  =

proofs there will not be any runtime error or specification violation.  =

Obviously, this is welcome in critical areas... while not only.

There is no need to deal with a critical area to seek for that : this ma=
y  =

simply be because you want better as much as it is possible or because y=
ou  =

want something to be well-done as much as it is possible. The exact same=
  =

reasons you have to choose a typed language instead of a non-typed one. =
 =

Many people do things, in some manner, with non-typed language. Just the=
  =

way its done differs, and not every body have the same requirements. Som=
e  =

have requirements which makes them say they don't need typed language.  =

Some don't agree with that. This depends on what the author wish.

By the way, the definition of hat a critical area is, does not seems  =

clear. Some ones may say =E2=80=9Cthis is critical=E2=80=9D while some o=
ther will not.

I like to say SPARK is a step above types and declarations. This seems t=
o  =

better cover its purpose, in my humble opinion.

There is even better than a pragma Assert: a SPARK --# check.
