Parser error returning from a function.

[ntrippar]

the is not parsing correctly if there is a empty return in a function.

POC:

function addClass(elem){
    return
}

use boa::syntax::lexer::Lexer;
use boa::syntax::parser::Parser;
use std::fs;

fn main() {
    let buffer = fs::read_to_string("test.js").unwrap();
    let mut lexer = Lexer::new(&buffer);
    lexer.lex().expect("failed to lex");
    let mut parser = Parser::new(lexer.tokens);
    println!("{:?}", parser.parse_all());
}

Error:

Err(Expected([], Token { data: Punctuator(CloseBlock), pos: Position { column_number: 1, line_number: 3 } }, "script"))
