Thank you, that's very interesting. I'm still a bit sceptical about
this static-sized internal structures thing, though. Isn't programming
without dynamic allocation difficult? Last time I did it was in
Commodore Basic, and that's because I didn't know how to do it then :-)

I would think that some software (for instance the browser and
windowing system I'm using now) would be practically impossible to
write in SPARK or similar languages?
