| 41 | <span class="emphasis"><em>Binding</em></span> is the act of tying together a function to some | |
| 42 | arguments for deferred (lazy) evaluation. Named <a class="link" href="function.html" title="Function">lazy | |
| 43 | functions</a> require a bit of typing. Unlike (unnamed) lambda expressions, | |
| 44 | we need to write a functor somewhere offline, detached from the call site. | |
| 45 | If you wish to transform a plain function, member function or member variable | |
| 46 | to a lambda expression, <code class="computeroutput"><span class="identifier">bind</span></code> | |
| 47 | is your friend. | |

| 55 | Take note that binding functions, member functions or member variables | |
| 56 | is monomorphic. Rather than binding functions, the preferred way is to | |
| 57 | write true generic and polymorphic <a class="link" href="function.html" title="Function">lazy | |
| 58 | functions</a>. | |

| 62 | There is a set of overloaded <code class="computeroutput"><span class="identifier">bind</span></code> | |
| 63 | template functions. Each <code class="computeroutput"><span class="identifier">bind</span><span class="special">(</span><span class="identifier">x</span><span class="special">)</span></code> | |
| 64 | function generates a suitable binder object. | |
