== Description


Upon construction, this acquires        exclusive access to an object of type        `T` which is either recycled from the        specified bin, or newly allocated.        The object is in an unknown but        valid state.


=== Example

[,cpp]
----
static recycled< std::string > bin;

recycled_ptr< std::string > ps( bin );

// Put the string into a known state
ps->clear();
----

=== Postconditions

[,cpp]
----
&this->bin() == &bin && ! this->empty()
----


== Parameters
