== Description


This is a smart pointer container which can    acquire shared ownership of an instance of    `T` upon or after construction&period; The instance    is guaranteed to be in a valid, but unknown    state&period; Every recycled pointer references    a valid recycle bin&period;


=== Example

static recycled< std::string > bin;

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

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