@trusted is exactly for that. It can be called from @safe code:

@trusted @nogc ubyte[n] rand_bytes(uint n)() {
    // ...
}

@safe auto foo() {
    return rand_bytes!3();
}

Thanks! So @trusted is me guaranteeing to the compiler that this 
function is safe? Is there any way of auditing this code through 
valgrind, etc. Also, thanks a lot for your book on D. It has been 
an invaluable resource in getting me started.
