Unhelpful error message with missing semicolon

[jruderman]

fn main()
{
    let x = 3
}

gives me

/Users/jruderman/Desktop/unhelpful_parse_error_missing_semi.rs:4:0: 4:1 error: expected `` but found `}`
/Users/jruderman/Desktop/unhelpful_parse_error_missing_semi.rs:4 }
                                                                 ^

It expected the empty string?

The lexer token stringifier was writing semicolons as empty strings.
