./arch/linux.i386-64/bin/ksh -o nounset -c 'bool -a b=( [4][5]=true )
; print $((b[4][5].true))'
./arch/linux.i386-64/bin/ksh: b[4][5].true: parameter not set
./arch/linux.i386-64/bin/ksh -o nounset -c 'bool -A b=( [lin]=true ) ;
print $((b[lin].true))'
./arch/linux.i386-64/bin/ksh: b[lin].true: parameter not set

There is no need for that to work since all elements of any array
are of the same type so that b.true works for an array element.

./arch/linux.i386-64/bin/ksh -o nounset -c 'bool -a b=( [4][5]=true )
; print $((b[4][5].true))'
./arch/linux.i386-64/bin/ksh: b[4][5].true: parameter not set
The reason why I want this to work are references, after which you can
./arch/linux.i386-64/bin/ksh -o nounset -c 'bool -a b=( [4][5]=true )
; nameref nb=b[4][5] ; print ${nb.true}'
./arch/linux.i386-64/bin/ksh: nb.true: parameter not set

Mhhh... I agree with Wendy that this should be fixed... otherwise it's
becoming very hard to implement some algorithms which operate on enums
with conditional use of namerefs. I just ran into that trouble when
working on the "bool.sh" testsuite module (the same should work for
associative bool arrays, too).
