local associative array seen as global

For bugs

• Rule Id: SC2190
• My shellcheck version (shellcheck --version or 'online'): online and local version 0.7.1
• I tried on shellcheck.net and verified that this is still a problem on the latest commit
• It's not reproducible on shellcheck.net, but I think that's because it's an OS, configuration or encoding issue

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

#!/bin/bash

f() {
   local -A map
   map[x]=assoc
   map[y]=array
   echo "local map: ${map[*]}"
}

g() {
   local -a map
   map+=(index)
   map+=(arr)
}

f
echo "x: ${map[x]} y: ${map[y]}"
g
echo "global map: ${map[*]}"

Here's what shellcheck currently says:

Line 12	SC2190: Elements in associative arrays need index, e.g. array=( [index]=value ) .
Line 13	SC2190: Elements in associative arrays need index, e.g. array=( [index]=value ) .

Here's what I wanted or expected to see:

it should give error code SC2034 instead: map appears unused. Verify...
