public class LetNode extends Scope
Token.LET or Token.LETEXPR.
LetStatement:
let ( VariableDeclarationList ) Block
LetExpression:
let ( VariableDeclarationList ) Expression
Note that standalone let-statements with no parens or body block,
such as let x=6, y=7;, are represented as a
VariableDeclaration node of type Token.LET,

AstNode
Note: if the parser was in error-recovery mode, some AST nodes may have
null children that are expected to be non-null
when no errors are present. In this situation, the behavior of the
toSource method is undefined: toSource
implementations may assume that the AST node is error-free, since it is
intended to be invoked only at runtime after a successful parse.
