False positive: SC2190 Elements in associative arrays need index

For bugs

SC2190
0.8.0 and online
[x] The rule's wiki page does not already cover this (e.g. https://shellcheck.net/wiki/SC2086)
[x] I tried on https://www.shellcheck.net/ and verified that this is still a problem on the latest commit

For new checks and feature suggestions

[ ] https://www.shellcheck.net/ (i.e. the latest commit) currently gives no useful warnings about this
[ ] I searched through https://github.com/koalaman/shellcheck/issues and didn't find anything related

Here's a snippet or screenshot that shows the problem:


#!/usr/bin/env bash

declare -A q

q=( "k1" "v1" "k2" "v2")

echo "${q[k1]}"

Here's what shellcheck currently says:

Line 5:
q=( "k1" "v1" "k2" "v2")
    ^-- SC2190 (warning): Elements in associative arrays need index, e.g. array=( [index]=value ) .

                   ^-- SC2190 (warning): Elements in associative arrays need index, e.g. array=( [index]=value ) .

Here's what I wanted or expected to see:

Code OK

Bash man page says

When assigning to an associative array, the words in a compound assignment may be either assignment statements, for which the subscript is required, or a list of words that is interpreted as a sequence of alternating keys and values: name=( key1 value1 key2 value2 ...). These are treated identically to name=( [key1]=value1 [key2]=value2 ...). The first word in the list determines how the remaining words are interpreted; all assignments in a list must be of the same type. When using key/value pairs, the keys may not be missing or empty; a final missing value is treated like the empty string.

It means the syntax var=( key val key val ) is valid.

Please, update the code and the wiki page https://github.com/koalaman/shellcheck/wiki/SC2190

Thank you.
