Unused function parameter in lambda function about phpcs-variable-analysis HOT 4 CLOSED

Interesting! It looks like something to do with the array access which is breaking this. The bug does occur in the expression:

do_something(fn($array, $needle) => $array[2] === $needle);

But it does not occur in:

do_something(fn($array, $needle) => $array === $needle);

I think that there's a bug in how we detect the scope of an arrow function which contains a bracket.

#296 should fix this.

Thanks @sirbrillig - that was a quick fix & release!!
Working perfectly now.

Turns out the fix was really easy: just stop letting phpcs do its own scope detection for arrow functions. 😁
