"cargo test" autocompletion gets an error

[saghm]

On zsh, when I type cargo test and then press tab, instead of autocompleting the names of the tests, the error _test_names:3: bad pattern: ![[ gets printed out. This is actually more annoying than if cargo just didn't attempt to complete my test names at all. Any idea if this is happening because of something on cargo's end rather than zsh?

This was a bug in the autocompletion script.

Awesome, thanks for getting on that!
