I was to ask you if you were really sure, ... you've already requested f=
or  =

more comments in the P.S., so may not give me an answer.
Well, you may also see a loop as an abstraction surrounded by pre and po=
st  =

and requires the previous state in some the same as the new one after ea=
ch  =

iteration (just a beginner's two cents idea)

I'm just starting with SPARK, so I may be wrong : it seems to me recursi=
on  =

is allowed if the stack usage is bounded (keep in mind I may be wrong).

pragma Asset ? Is that true ? Waaww... great
