Hi, Rick!

I couldn't agree with you more. GPC is a great step forward in a fight for 
diversity, if it isn't anything else. It would be very nice to have all 
kernel calls available in GPC via a library, so one could also write 
system programs in GPC. IMHO GPC is nowadays stable enough to succeed 
writing system programs, and it is possible that such programs would be 
more reliable! (cosider only range checking vs. C's dangerous pointers 
that always shoot somebody in his leg).

Your thinking is enouraging me to attempt writting very system software 
for Linux in GPC. After all, installing GPC is now as easy as installing 
.deb or .rpm, isn't it?

I agree with you that stability is much more important than "new" things 
when writting system-level software.

Have a nice day,
Mirsad
