Comment (by johnbillion):

 Oh I forgot to add there's also a shorter `list<string>` syntax for lists
 (arrays with sequential integer keys), and while this is well supported in
 static analysis tools it's much less supported in editors and IDEs. The
 Intelephense extension for VS Code doesn't support it, for example,
 although PHPStorm does appear to. I recommend for now that we don't
 implement `list<>`.
