[Help-bash] Adding missing bash features for safely re-usable bash code

[adrelanos]

Hi!

Asking the other way around...

This doesn't look like something impossible to do, just like a missing
feature in bash.

What are the missing features in bash for writing easily, safely
re-usable bash code?

Could bash be extended with these missing features?

Who could patch bash?

Would the patch get accepted upstream?

Cheers!
