Variables not used for anything are often associated with bugs, so ShellCheck warns about them.
Also note that something like `local let foo=42` does not make a `let` statement local -- it instead declares an additional local variable named `let`.
### Exceptions
ShellCheck may not always realize that the variable is in use (especially with indirection), and may not realize you don't care (with throwaway variables or unimplemented features).
