The patterns used by <a href="/pkg/net/http#ServeMux"><code>net/http.ServeMux</code></a> have been enhanced to accept methods and wildcards.
</p>

<p>
  Registering a handler with a method, like <code>"POST /items/create"</code>, restricts
  invocations of the handler to requests with the given method. A pattern with a method takes precedence over a matching pattern without one.

<p>
A "for" statement with a ForClause is also controlled by its condition, but
additionally it may specify an <i>init</i>
and a <i>post</i> statement, such as an assignment,
an increment or decrement statement. The init statement may be a
<a href="#Short_variable_declarations">short variable declaration</a>, but the post statement must not.
Variables declared by the init statement are re-used in each iteration.
