I believe « declare -A assoc=("${kv[@]}") » should be supported [where
kv is an indexed array in the form kv=(key1 value1 key2 value2 ...)].

That thread discussed a slightly different behavior: The OP of that
thread expected "[x]=y" in the results of shell expansion to be
treated as assignments like « [key]=value ».

However, the present report discusses whether "key1 value1 key2 value2
..." in the results of shell expansion should be subject to word
splitting and cause the assignments of « [key1]=value1 [key2]=value2
».

It's similar, but it seems slightly different. The present report
seems to discuss a different point. « declare -A aa="( "${kv[@]}" )"»
and « declare -A aa=( "${kv[@]}" ) » are different.
