<p>Returns a string representation of the given object. </p>

<p>This function is defined for most containers provided by Hana, and also for objects that define an <code>operator<<</code> that can be used with a <code>std::basic_ostream</code>. It can recursively print containers within containers, but do not expect any kind of proper indentation.</p>
|
|
<p>This function requires (the rest of) Boost to be available on the system. It also requires RTTI to be enabled. </p>
