bash: not a bug, a feature .... (?)

export Q='() { a=$(pwd); [ -z "$Q_env" ] && export Q_env=$*; b=$Q_env; echo "a=$a, b=$b,"; }; Q $(pwd)'; bash -c "Q; cd ~/Desktop; Q"
It looks like this "feature" let us to "eval" and "bind" a lexical env at subshell start. For sure, it could have some 'legal' use ...
Sample Output
a=/home/gio, b=/home/gio,
a=/home/gio, b=/home/gio,
a=/home/gio/Desktop, b=/home/gio,

Your request looks a little bit vague. What if you elaborate more about what is that you need? When you are looking for developers for your apps, perhaps you should bear in mind whether you need project- or product-oriented people. Here https://orangesoft.co/blog/project-vs-product-mindset-in-software-development you can read more about it and what the advantages of each approach are. I think that the right focus will help you get the right result.
