package (and in fact on any object as well, although it's rarer that you'd
want to do that).
+Finally, we also provide an C<unimport::out_of> to allow the exporting of the
+effect of C<no>:
+
+ # unimport::out_of was added in 1.1.0 (1.001000)
+ sub unimport {
+ Moose->unimport::out_of(scalar caller); # no MyThing == no Moose
+ }
+
If how and why this all works is of interest to you, please read on to the
description immediately below.
And that's it.
