 * Swig_temp_result()
 *
 * This function is used to return a "temporary" result--a result that is only
 * guaranteed to exist for a short period of time.   Typically this is used by
 * functions that return strings and other intermediate results that are
 * used in print statements.
 *
 * Note: this is really a bit of a kludge to make it easier to work with
 * temporary variables (so that the caller doesn't have to worry about
 * memory management).   In theory, it is possible to break this if an
 * operation produces so many temporaries that it overflows the internal
 * array before they are used.   However, in practice, this would only
 * occur for very deep levels of recursion or functions taking lots of
 * parameters---neither of which occur very often in SWIG (if at all).
 * Also, a user can prevent destruction of a temporary object by increasing
 * it's reference count using DohIncref().
 *
 * It is an error to place two identical results onto this list.  It is also
 * an error for a caller to free anything returned by this function.
 *
 * Note: SWIG1.1 did something similar to this in a less-organized manner.
