I'm asking for overflow detection for years (both at compile-time and
run-time).

Again here the C language is better than the D language:

// C code
#include "stdio.h"
int main() {
    long long x = 1024 * 1024 * 1024 * 6;
    printf("%lld\n", x);
    return 0;    
}


GCC 4.3.4 gives:
prog.c: In function ‘main’:
prog.c:3: warning: integer overflow in expression

D compiler is not _practical_ enough yet.
