# self-assignment

**Default severity:** `warning`

Assigning a side-effect-free expression to the identical destination does
nothing and usually indicates a mistaken variable on one side. Expressions
with effectful calls or channel receives are excluded because evaluating them
can change state.

## Bad

```go
current = current
```

## Good

```go
current = next
```
