Because I need the scripts and snippets I write for my repos to work for other developers, I'm going to write them to be bash compatible. That applies also to scripts and snippets written by others that I consume.

So if a shell is not bash syntax compatible, then it really has to offer some astonishingly useful features to offset my having to translate and map the scripts I need to run for it.

Murex does not interpret "$(cmd args)". So unfortunately, I cannot use it. I know it's not fair, and I know that is promoting a lock-in of what shells can do, but I need to get shit done I'm afraid.

Interesting. Looks similar to nushell [1] which also is data-encoding-aware.

Wasn't Murex some sort of backend software for financial institutions?

Maybe I’m just not the target audience, but looking at the front page, I don’t see what actual problems this solves. The claims sound nice, but without examples of what they mean in real world use, it’s not really compelling.

It looks like PowerShell, or nushell that also looks like PowerShell.

Did you know you can install PowerShell on Linux too?

What happened to the convention that shell names end in sh? There are:

    grep sh$ /usr/share/dict/words | wc -l
        1959

This looks interesting, I will consider switching if it's not sluggish like zsh was that one day I tried it.

A few of those ideas are also in https://www.nushell.sh/
