# address-nil-comparison

**Default severity:** `warning`

Taking the address of an addressable value produces a non-nil pointer whenever
evaluation completes, so comparing that address with `nil` has a fixed result.

The `&*pointer` form is excluded because it simplifies to `pointer`, which may
legitimately be nil.

## Bad

```go
if &value == nil { handle() }
```

## Good

```go
if pointer == nil { handle() }
```
