Is there a difference in the execution speed and stability when

argument like this?
the generated code the processor sees is generally identical, but the
`ref` version is potentially better because then X cannot possibly be
`null` which can help you write better code and might help the optimizer
too.
still, using explicit pointers may be good for readability.
int a;
foo(a); // does it chage `a`?
boo(&a); // oh, yeah, now i see that it will prolly change `a`
unsafe coding style, but for me pointers for `ref` are more readable.
