Cannot use turbofish syntax in template

[OskarPersson]

The following template code does not work:

<p>@books.into_iter().map(|b| b.title).collect::<Vec<String>>().join(", ")</p>

and results in the following error

  --> C:\Users\oskar\git\books-rs\target\debug\build\books-rs-44f2c21020dbf42e\out\templates\template_books_html.rs:12:46

Yes, the turbofish makes the expression to complex to use without enclosing parenthesis. You can fix it by enclosing the entire expression in parenthesis:

<p>@(books.into_iter().map(|b| b.title).collect::<Vec<String>>().join(", "))</p>

The error message for this could be better (as could all error messages from the generated code), but I don't know how to do that.
