>||</code> are not supported as
overloadable operators.</p>
<p>Many of the operators take their operands by value. In non-generic
contexts involving built-in types, this is usually not a problem.
However, using these operators in generic code, requires some
attention if values have to be reused as opposed to letting the operators
consume them. One option is to occasionally use <a href="../clone/trait.Clone.html#tymethod.clone"><code>clone</code></a>.
Another option is to rely on the types involved providing
