What would the chances be of sometime in the future of getting a patch (or
getting it integrated into the main tree) so that the
`expr ! ERR => value' stuff would take any value in place of the error?
So you could do something like
x = `#obj:verb() ! E_PERM, E_VERBNF, 0 => 1'; or such
It seems to me that it would be very useful to add the functionality if it
would be at little cost.
