Should we say:

sorry, just a glitch that I didn't write SHOULD, really.

I'm wondering if saying that "Numbered variables can not be set" is made 
redundant by your comments that an extension should state whether its 
namespace is modifiable with the set action.  Certainly it feels quite 
restrictive to have it said in both places.

there's no namespace for numbered variables, so I don't think it is
redundant.
