What does "append" mean when the keys are specified?  If I have

arr=( 1 2 3 4 5 )

and I do

arr+=( 6 [2]=7 8 )

does that even make sense?  That's certainly not "appending" to arr[2].

The other point that this raises is that in ksh "typeset -p" of an associative
array outputs e.g.

typeset -A x=([y]=2 [z]=1)

and that's the only way to assign an associative array; if you assign without
the [k]=v syntax the parameter converts into an ordinary array.  Is this going
to get enforced when KSH_ARRAYS and/or KSH_TYPESET are in effect?
