# Statements

## Block statement

```go
blockStmt := '{' decl* '}'
```

A block is a list of declarations, so you can declare variables in side this statement. We put it between two curly braces.

## Return statement

```go
returnStmt := 'return' ( '\n' | expr )
```

If a newline occurs after "return", that means the function returns none. Otherwise, requires an expression.

## While statement

```go
whileStmt := 'while' expr blockStmt
```
