Still same to me.

Backticks are not very distinct, as they can be confused with single quotes (depending on the font). Also $() shows the beginning and end of the command very clearly. This is even more important when you have multiple of them in some variable in example. Not to mention that you can nest $(), but that is something I personally don’t like to do anyway.

There are some functional differences too: https://www.gnu.org/software/bash/manual/html_node/Command-Substitution.html , such as that backtick command set as an alias in your bashrc will be executed once on load. While $() version is executed every time you execute the alias. Also backslash is literal in the backtick variants (with exception). All in all I never use backtick command substitution; it’s confusing, limited and deprecated.

!(r.SendNow || r.DryRun) requires you to read the entire statement and then negate the result. While !r.SendNow && !r.DryRun each part of the statement stands on its own and is negated for themselves. That is how I read. I like the Ai suggestion more, because that is how I would write it myself. What I like about it is, that the negation of is right there with the variable. It gets more important, the more you divide sub-expressions in multiple lines.

Well that wasn’t meant to be too serious. You are surely aware of the situation that Haskell is not often used language in production. And a huge project you are doing with lot of Haskell is definitely something special.

he’s very familiar with C and C++. In his associated writeup on his Gopher page (link though Floodgap) [jns] simply declares it’s a language he’s quite fond of, which is reason enough of us.

So there are no technical reasons to do so. Its totally understandable to like and use a language for personal feelings. But it kinda feels like unnecessary complicated. So this should be done as a hobby project on something that is not important in my opinion.

Make it in Haskell if you want impress me.

I also recommend to read the source code: https://github.com/rolflobker/recall-for-linux/blob/main/recall-for-linux.exe
