-Properties work as detailed in S12.  They're actually object
-attributes provided by role mixins.  Compile-time properties applied
-to containers and such still use the C<is> keyword, but are now called
-"traits".  On the other hand, run-time properties are attached to
-individual objects using the C<but> keyword instead, but are still

-Properties are accessed just like attributes because they are in fact
-attributes of some class or other, even if it's an anonymous singleton
-class generated on the fly for that purpose.  Since "C<rw>" attributes
-behave in all respects as variables, properties may therefore also
-be temporized with C<temp>, or hypotheticalized with C<let>.
