} That's related to my previous fix --- x=() causes x to be marked as an
} array but with no value, not just an empty list.

Thanks for the patch, but it still doesn't address my second point:

This works for scalars, i.e.

torch% typeset x=abcd x[1]=1 x[3]=3
torch% typeset -p x
typeset x=1b3d
torch% typeset x='' x[2]=2 x[4]=4
torch% typeset -p x              
typeset x=24
torch% 

Note that I did NOT get x=1234 out of that last.
