When declaring ``associative array'', I alway use ``quoted'' syntax:
$ foo='1 2'
$ declare -A bar='($foo 3)'
$ declare -p bar
declare -A bar=(["1 2"]="3" )
Not sure how to explain this, but I'm not surprised seeing this working so.
$ bar+=($foo 3)
$ declare -p bar
declare -A bar=(["1 2"]="3" )
Seem ok for me!
