Seems like I am just too radical for ya'll:

static const double d = 3.1415;

int main() {
        foo(d);
}

I asked my C compiler, it like it, it knew what it meant, it knew how 
to optimize it, it _liked_ it, and until we make that an error...  I 
don't think C++ should be radically different, anyway, I've already 
agreed with Gaby that the better forum is the C++ committee, and I'm 
content to not push the issue here.  I've already yelped, and that's 
all I'm gonna do.

The above C program seemed to work in C++ as well.  Either, that is a 
bug in C and C++, or somewhere, it is defined well enough to work.
