So it is no longer advisable to store something in t[0] if you want to
use #t?  Would it be possible to change that to "positive numeric
keys", at least?

      

The present implementation makes #t well-defined and equal to n if all 
its positive integer keys comprise the set {1..n}.  That would not be
a problem.
    

You are using "present implementation" and "well-defined" in a
nonsensical combination.  It's like trying to have your cake recipe and
eat it too.  
  

Just that that is the problem. The recipe is showing in the cake.
