Function Statement Swift (Swizzle)

public final class FunctionStatement: Statement, CustomStringConvertible {
    public let name: Token
    public let args: [ParameterStatement]
    public let body: [Statement]
    public let returnType: Token
    public init(name: Token, args: [ParameterStatement], body: [Statement], returnType: Token = Token(type: .identifier, lexme: "Void", literal: nil, line: nil)) {
        self.name = name
        self.args = args
        self.body = body
        self.returnType = returnType
    }
    public var description: String {
        return "\(name.lexme)(\(args.joined()) -> \(returnType.lexme)"
    }
    public override func accept<V, R>(_ visitor: V) throws -> R where V : Visitor, R == V.Result {
        return try visitor.visit(self)
    }
