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!
