it. Here's the full version.)
Some single quotes...
`let` is more consistent with them:
$ unset A; a=" ";declare -A A; let "A['$a']++"; declare -p A
declare -A A=([" "]="1" )
$ unset A; a=" ";declare -A A; let "A[''$a]++"

1. `let` is more consistent with them:
$ unset A; a=" ";declare -A A; let "A['$a']++"; declare -p A
declare -A A=([" "]="1" )
$ unset A; a=" ";declare -A A; let "A[''$a]++"; declare -p A
declare -A A=([" "]="1" )
$ unset A; a=" ";declare -A A; let "A[$a'']++"; declare -p A
