| We need to utilize <code class="computeroutput"><span class="identifier">proto</span><span class="special">::</span><span class="identifier">deep_copy</span></code> |
| as the expression contains literals (the <code class="computeroutput"><span class="char">'{'</span></code>, |
| <code class="computeroutput"><span class="char">','</span></code>, and <code class="computeroutput"><span class="char">'}'</span></code>) |
| which normally get embedded in the proto expression by reference only. |
| The deep copy converts the proto tree to hold this by value. The deep copy |
| operation can be left out for simpler proto expressions (not containing |
| references to temporaries). Alternatively you could use the <code class="computeroutput"><span class="identifier">proto</span><span class="special">::</span><span class="identifier">make_expr</span></code> facility to build the required |
| proto expression. |
