# Go grouped declarations

Group related declarations using `type ()`, `const ()`, and `var ()` blocks.

```go
// GOOD — grouped type block
type (
	CreateFooRequest struct {
		Name   string
		Active bool
	}

	UpdateFooRequest struct {
		ID     gid.GID
		Name   *string
		Active *bool
	}
)

// GOOD — grouped const block
const (
	NameMaxLength    = 100
	ContentMaxLength = 5000
)

// GOOD — interface satisfaction checks
var (
	_ Reader = (*FileReader)(nil)
	_ Writer = (*FileWriter)(nil)
)
```

## String enums

Use explicit typed string values, **not** `iota`:

```go
// GOOD
type Status string

const (
	StatusActive   Status = "active"
	StatusInactive Status = "inactive"
)

// BAD — iota for string-like enums
type Status int

const (
	StatusActive Status = iota
	StatusInactive
)
```
