Perhaps you should check the code, because they are *not* stored 
separately from each other.  In the current revision, :vtable and 
:method used together stores the sub as a vtable entry and as a visible 
method.  Adding :anon detaches it from the namespace.  For the new PDD15 
implementation, once #42406 and #42407 are committed, I plan to rework 
how they're stored internally, but that isn't relevant to our discussion 
of the interface.

Yes, that's how they're implemented now. Currently, in order to use the 
common feature of overriding the vtable entry without polluting the 
namespace you have to specify ":vtable :method :anon". Which is huge 
progress over what we had before (you used to override a vtable by 
creating a .sub prefixed with "__").

I'm talking about how they will be implemented for PDD15. Methods and 
vtables will be stored separately, because it will be quite common to 
have vtable entries with no corresponding method, and methods with no 
corresponding vtable entry. The interface is intended to reflect the 
same fact.
