I would say that there's something wrong with a procedural (or
functional) language that still uses dynamic scoping by default.
Dynamic scoping itself is a very useful tool when used at appropriate
times, and there's a reason it sticks around in languages like Common
Lisp and Scheme as an alternative to the default static scoping.
For whatever reason, shell essentially stopped evolving as a scripting
language a long time ago. Probably due to the desire for
compatibility. It's a shame we're stuck with such a lousy, worthless
piece of garbage language as the default today.
