Please note that the memory address is *NOT* fixed for the lifetime of an
object. Garbage collection may move it to another memory location at *any*
time. I've therefore adapted the documentation of .WHERE to:
Returns an C<Int> representing the memory address of the object. Please note
that in the Rakudo implementation of Raku, and possibly other implementations,
the memory location of an object is B<NOT> fixed for the lifetime of the
object. So it has limited use for applications, and is intended as a debugging
tool only.
