<para>
The <code>template &lt;typename K&gt;</code> overload only participates
in overload resolution if <code>Hash::is_transparent</code> and
<code>Pred::is_transparent</code> are valid member typedefs. The
library assumes that <code>Hash</code> is callable with both
<code>K</code> and <code>Key</code> and that <code>Pred</code> is
transparent. This enables heterogeneous lookup which avoids the cost of
instantiating an instance of the <code>Key</code> type.
