It doesn't work in ksh 93v- 2013-08-05:
./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
no longer differ between plain bool and array element book:
./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
/arch/linux.i386-64/bin/ksh -o nounset -c 'bool b ; nameref nb=b ;
print ${nb.true}'
1
There is a 3rd bug:
./arch/linux.i386-64/bin/ksh -o nounset -c 'bool b ; print
"${b.true},$((b.true))'
1,1
It should print true,1 and not 1,1
${b.true} is not expanding to a true/false string as I need it.
