Bash 1.14 from 1992 incorrectly fails this test. This was fixed for Bash 2.0 in 1996:
```sh
var='!'
[ "$var" = "!" ]
```
Dash 0.5.4 from 2007 incorrectly passes this test. This was fixed for Dash 0.5.5 in 2008:
```sh
x='(' y=')'
[ "$x" = "$y" ]
```
Zsh (while not supported by ShellCheck) fixed the same problem in 2015.
