I'm aware of the pitfalls described therein, and more. I don't think anyone thinks multiple evaluation in indexes is good per se, but many find the side effects of the attempted cures worse than the disease (e.g., https://mywiki.wooledge.org/BashPitfalls#pf62).
In its zeal to demonstrate how bad bash is, that little code snippet
ignores the obvious solution:
declare -A hash
key=\'\]
hash[$key]=17
(( hash[key]++ ))
declare -p hash
Since arithmetic evaluation performs its own expansion of identifiers.
assoc_expand_once also works. But that wasn't really the point, was it?
