.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a more robust way of making sure any cached memory is freed, as it
will be handled by the last \f(CW\*(C`MemFree\*(C'\fR object leaving scope.  This means if
your routines were inside an eval that died, things will still get cleaned up.
If you call another function that uses a MemFree object, the cache will stay
in place because you still have an object.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.SS "new"
.IX Subsection "new"
Creates a new auto-free object.  This object has no methods and has no data.
When it leaves scope it will call \f(CW\*(C`prime_memfree\*(C'\fR, thereby releasing any
extra memory that the Math::Prime::Util module may have allocated.
.PP
Memory is not freed until the last object goes out of scope.  \f(CW\*(C`prime_memfree\*(C'\fR
may always be called manually.  All memory is freed at \f(CW\*(C`END\*(C'\fR time, so this is
mainly for long running programs that want extra control over memory use.
