  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.
  As a special case, registering a handler with <code> "GET"</code> also registers it with <code>"HEAD"</code>.

Reads of memory locations larger than a single machine word
are encouraged but not required to meet the same semantics
as word-sized memory locations,
observing a single allowed write <i>w</i>.
For performance reasons,
implementations may instead treat larger operations
as a set of individual machine-word-sized operations
in an unspecified order.

Type unification is controlled by a <i>matching mode</i>, which may
be <i>exact</i> or <i>loose</i>.
As unification recursively descends a composite type structure,
the matching mode used for elements of the type, the <i>element matching mode</i>,
remains the same as the matching mode except when two types are unified for
