# odd-paired-arguments

**Default severity:** `error`

Some functions consume slice or variadic elements in pairs and reject odd
lengths. The check recognizes standard pair-oriented APIs and local
functions that enforce an even length by panicking, then checks calls whose
argument length is statically known.

## Bad

```go
strings.NewReplacer("old", "new", "orphan")
```

## Good

```go
strings.NewReplacer("old", "new")
```
