I like the idea of shell blocks.
Looks like you can get something similar in Rust with cmd_lib[1].

In Hush, a modern shell scripting languageHere is the rust library with the “the only good parts” of bash/shell script: https://github.com/rust-shell-script/rust_cmd_lib
In Bash functions are better than I thoughtShellCheck and templates from the Shell Field Guide[1] is what keeps my bank running.
Rust cmd_lib[2] is tempting with safety, though tougher maintainability.

[2] https://github.com/rust-shell-script/rust_cmd_lib
In ShellCheck: Finds bugs in your shell scriptsThe only good part of sh/bash script is to run commands with piping/redirection support IMO，other than that I saw posts like this to explain sh/bash script’s puzzles/pitfalls all the time.
Maybe it is time to consider using rust instead: https://github.com/rust-shell-script/rust_cmd_lib ?
In What was the point of [ “x$var” = “xval” ]?zsh is also doing the variable substitution better than bash. FYI, I just released rust_cmd_lib 1.0 recently, which can do variable substitution without any quotes: https://github.com/rust-shell-script/rust_cmd_lib

I have created a similar library for bash. However, there are more pitfalls related to errexit, see [1] and even shellcheck can not help there. I have tried to solve the pitfalls in my library, but it turned out to be ugly and unreliable. That's why I'm trying to use rust [2] for shell scripting like tasks nowadays.

In Show HN: Using Rust to write shell-script like tasksSince macros can execute arbitrary code, this makes me feel uneasy that the strings are just executed within a shell context, with all the appropriate, bug-prone, expansion done by the shell.
Its a shame you didn't bother to look at the source code before criticizing. Someone put a lot of work into this library and its actually pretty cool.
The package parses the code in the macros [1] and then calls 'std:Process::Command' [2] which, I believe, does not execute a subshell by default.
