Maybe you were expecting something that SPARK is not. SPARK is not a
replacement for Ada. SPARK is designed for highly secure software. You
won't create a Web server, an XML parser or even some kind of simulation
and GUI with it. In those application domains you need full Ada (binding
to external libraries, generics, full OO, standard libraries Ada.*,
Interfaces.* and possibly GNAT.*, full text and stream IO...).

I had to create a binding to the OS sockets in SPARK, I can tell you
that it was not easy... Especially as this was my first experience with
SPARK!

For embedded control-command application that's another story. I think
that SPARK has something invaluable to offer.

I have also thought that you can mix SPARK and Ada in the same
application. Using SPARK in the critical part, and Ada for the rest...
Don't know how well this would work as I have not gone through this yet.

Just my 2 cents of course!

Pascal.
