The point is NEITHER one of them does what everyone expects.
hobbit:~$ kv=(one 1 two 2 "two and a half" 2.5 three 3)
hobbit:~$ declare -A aa=("${kv[@]}"); declare -p aa
declare -A aa=(["one 1 two 2 two and a half 2.5 three 3"]="" )
hobbit:~$ declare -A aa="("${kv[@]}")"; declare -p aa
declare -A aa=([3]="" [a]="half" [two]="and" [2.5]="three" [one]="1" )
Both of these are "wrong" from the point of view of everybody but Chet.
It doesn't appear this is going to change.
The only known workaround is to abandon this approach entirely, and use
@K plus eval instead.
