Literal that is not closed

Built from the repository at commit a8614dc.

A char literal ends with a ' on the line it starts on, and a string literal with a " on the line it starts on, interpolations included. A line break or the end of the file before that quote is an error, reported at the opening quote. Write \n for a line break in a string. A { starts an interpolation, so in "x{" the second " opens a new literal inside it; write \{ for a literal brace.

Why

The compiler cannot tell where the literal should have ended, so it offers no fix.

Broken

fn main() {
    let c = 'a
    print(c)
}

Fixed
