For what it's worth I think the fact they did it in C is one of it's best
features.. and like others have said, you can always add wrappers for C++.


Something interesting to think about :)


imain@slow:~$ cat hello_world.c 
#include <stdio.h>

int main(void)
{
        printf("hello world\n");
        return(0);
}


imain@slow:~$ gcc hello_world.c -o hello-c

imain@slow:~$ g++ hello_world.c -o hello-cc

imain@slow:~$ time hello-c
hello world

real    0m0.126s
user    0m0.010s
sys     0m0.010s

imain@slow:~$ time hello-cc
hello world

real    0m0.671s
user    0m0.040s
sys     0m0.060s


This is linux 2.0.30 with all the latest  - gcc version 2.7.2.1.. I'm sure
it's the linktime for the C++ version that kills it..
