What a Zsh linter should do?

[Sebastian Gniazdowski <sgniazdowski@gmail.com>]

Hello!
I'm wondering about functionality of a possible Zsh linter. Let's say
that the general idea is similar to shellcheck.

I think that the standard functionality – telling user to write a
nicer code – isn't a good one for Zshell. For example: telling user to
use `if' instead of [[ ... ]] && { ... ((1)); } || { ... } – I think
this is wrong for Zshell, where the "density" of code increases as
skills increase, and the programmer is e.g. being able to write a
"dense" one-liner utilizing :-, :+, :#, (M) instead of multi-line
if/else or even [[ ]] && { } || { }.

So what could a Zsh linter actually do?
