How come [][[]] is a lintable syntax is a still a mystery to me.

@dseguy I guess [[]] is an edge case hard to exclude from the « generic » rule? Because something like this is valid and doesn’t produce any warning:

var_dump([][![]] ?? 'default');

🤷

@b_viguier I am leaning toward 'it's not worth the effort'.

[][![]] is valid code (! cast the [] to boolean).

[][[]] Is not valid from the lint.

const A = []; [][A] ; is not valid but needs execution.

The border between the last two lines is very gray.

@dseguy can [] be transformed into 0 some how?

@wyri Which []? There are too many of them!

It is a fatal error, no type juggling. You need to force (cast) the type to make this to run.

array()[ array() ] is at least a bit more readable. 😂

@dseguy The second array() in your last line 😅
