Bash also has a loadable extension that can be used to load a dynamic
library. I think that it should be able to make gawk as a bash
loadable to reduce the startup time of gawk. See below---gawk startup
time is much slower than a bash function or a bash built-in command.

Will it cause any problem to make gawk a bash loadable module (e.g.,
could it conflict with the extension loading facility in gawk)?
Thanks.

$ cat ./main.sh
#!/usr/bin/env bash

function f {
    :

TIMEFORMAT=%R

do
    f
done
time for ((i=0;i<100;++i))
do
    echo -n
