After your answer, I checked and I think the error message is not
related to the variable name collision :

[a...@axel-asus plugins]$ unset foo
[a...@axel-asus plugins]$ func()

{
echo "[a]=5 [b]=10"
}

[a...@axel-asus plugins]$ declare -A foo=( $(func) )

$ declare -A foo=('[a]=5')

   Drop the qotes:

declare -A foo=( [a]=5 )

bash: foo: [a]=5: must use subscript when assigning associative array
$ eval "declare -A foo=($(echo '[a]=5'))"; echo ${foo[a]}
5
