Re: const static initializers versionitis

[Gianni Mariani <gianni at mariani dot ws>]

I don't know how to "export" a symbol from an anonymous
namespace.  But somthing like that would make this ANS's
viable.

$ g++ -c yy.cpp
yy.cpp:20: parse error before `('

------------ yy.cpp ------------
namespace {

struct foo {
        const struct foo * y;
        char    who[ 10 ];
};

extern const struct foo bar[];

extern const struct foo tar[];

const struct foo bar[] = {
        tar, "bar"
};

const struct foo tar[] = {
        bar, "tar"
};

const char * ::zefuc()
{
        return tar->y->who;
}

};
