This one is good to know. I was wondering about it these last few days  =

(was also wondering about a good choice to generate this, may be a scrip=
t  =

language). Sometime, automatically generated sources seems difficult to =
 =

avoid, even when one do not really enjoy the idea of preprocessor (may b=
e  =

some resilient fears due to older bad experiences with C). This may  =

happens when an application has multiple parts using different languages=
  =

or representations, and in the mean times must have some of their parts =
 =

synchronized in some way. Ex. an application with an Ada or Pascal part,=
  =

and HTML pages, and some JavaScript parts ; all with references to some =
 =

kind of protocols, identifiers, standard data which may need to be  =

changed, etc. Different worlds, which may refer to common stuffs. This i=
s  =

probably better when these dependencies are handled via automatic source=
  =

generation using a single data source.

I was wondering about reliability of automatically generated parts. Your=
  =

comment is interesting in this area.

-- =

There is even better than a pragma Assert: a SPARK --# check.
--# check C and WhoKnowWhat and YouKnowWho;
--# assert Ada;
--  i.e. forget about previous premises which leads to conclusion
--  and start with new conclusion as premise.
