# identical-binary-operands

**Default severity:** `warning`

Comparisons and non-idempotent operations with identical expressions on both
sides are usually copy-and-paste mistakes. Floating-point expressions are
excluded because `NaN` makes self-comparisons meaningful.

## Bad

```go
if left == left { use() }
```

## Good

```go
if left == right { use() }
```
