Lint/ShadowingOuterLocalVariable doesn't warn when a function parameter named it takes precedence over an implicit it in a block.

Describe the solution you'd like

Warn about it (pun intended).

Describe alternatives you've considered

Rather, warn about using it as a function parameter, which seems like asking for trouble in the first place.

Additional context

I love it.
