Here is a Bash model of how, associative array support could be added to
mapfile, replacing the need for interpreted while-loop read and logic by
a much more efficient improved mapfile built-in:
#!/usr/bin/env bash
kv_cr_stream () {
printf 'key1=value1\nkey2=value=2\nkey 3=value3\n'
}
kv_

Thanks for the proposal. I'll consider it for a future version
Here is an include shim to enable associative array support to mapfile
or fall-back to regular mapfile if it has that support already:
#!/usr/bin/env bash
# mapfile_assoc_shim.bash
! { mapfile -A a /dev/null && {
mapfile () {
local k v d=$'\n'
local -n A=${*: -1:1}
[[ ${*: -2:1} =
Shorty shim:
! { mapfile -A _/dev/null&&{ mapfile(){ local k v
d=$'\n';local -n A=${*: -1:1};[ ${*: -2:1} = -A ]&&{ [ ${*:1:1} = -d
]&&d=${*:2:1};while read -rd "$d" k v||[[ -n $k && -n $v ]];do
A[$k]=$v;done;:;}||command mapfile "$@";};}

Thanks for the propos
you can maybe implent dynamical runtime code decisons like runtime code for
splitting definement

One problem I see with it is that it assumes the introduction of word
splitting into mapfile, with the burden on the user to ensure that there
are exactly two resultant fields.
It is just meant to be a replacement to looping on:
IFS= read -r -d k v

Maybe (it is clearly open to discussion), the associative array mapping
could be allowed to:
- skip blank/comment only lines (1)
- allow key without value
- optionally trim trailing comment (1)
Forgot about Bash built-in Regex engine:
- allow using a

According to the source, -R should be setting RLIMIT_RTTIME,
but it does not work:
bash-5.0$ ulimit -R
bash: ulimit: -R: invalid option
ulimit: usage: ulimit [-SHabcdefiklmnpqrstuvxPT] [limit]
..and looking at the above help, I notice letters I never saw.
Lets try them?
bash-5.0$ ulimit -b
bash
10 matches
