<li>The
<code>Intn</code>,
<code>Int31</code>,
<code>Int31n</code>,
<code>Int63</code>,
and
<code>Int64n</code>
top-level functions and methods from <code>math/rand</code>
are spelled more idiomatically in <code>math/rand/v2</code>:
<code>IntN</code>,
<code>Int32</code>,
<code>Int32N</code>,
<code>Int64</code>,
and
<code>Int64N</code>.
There are also new top-level functions and methods
<code>Uint32</code>,

uint(-1)     // -1 cannot be represented as a uint

to lay down explicit data into the instruction stream within a <code>TEXT</code>.
Here's how the 386 runtime defines the 64-bit atomic load function.
