Making this paragraph abstract helps.

<p>
In Go, a name is exported if it begins with a capital letter.
<p>
- <code>Pi</code> is an exported name, as is <code>PI</code>.
- The name <code>pi</code> is not exported.
+ <code>Foo</code> is an exported name, as is <code>FOO</code>.
+ The name <code>foo</code> is not exported.
<p>
Run the code. Then rename <code>math.pi</code> to <code>math.Pi</code>
and try it again.
