| 31 | You'll probably want to work with objects. There are lazy versions of constructor | |
| 32 | calls, <code class="computeroutput"><span class="keyword">new</span></code>, <code class="computeroutput"><span class="keyword">delete</span></code> | |
| 33 | and the suite of C++ casts. Examples: | |
| 34 | </p> | |
| 35 | <pre class="programlisting"><span class="identifier">construct</span><span class="special"><</span><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span><span class="special">>(</span><span class="identifier">arg1</span><span class="special">,</span> <span class="identifier">arg2</span><span class="special">)</span> <span class="comment">// constructs a std::string from arg1, arg2</span> | |
