I tried this with ast-ksh.2013-08-07 on SuSE 12.3/AMD64/64bit:
-- snip --
$ ksh -c 'set -o nounset ; typeset -T x_t=( integer i=9 ; function pr
{ printf "%d/%d\n" _.i _.__.j ; } ;) ; typeset -T y_t=( x_t x ;
integer j=5 ) ; compound c ; y_t c.v ; c.v.x.pr'
9//home/test001/bin/ksh: c.v.x.pr[1]: printf: __.j: is not an element of c.v.x
-- snip --
... does anyone spot an error or is this a bug ?
Dismanteling "_.__.j" ... "_" references the current object (an
"x_t"), "_.__" the parent (an "y_t") so "_.__.j" should reference
y_t's member variable "j" ... right ?

Bye,
