fn pretty_print_state_elems<A, 'tcx>(
    w: &mut impl Write, 
    analysis: &A, 
    elems: impl Iterator<Item = A::Idx>, 
    sep: &str, 
    line_break: Option<LineBreak>
) -> Result<bool> where
    A: Analysis<'tcx>, 

Formats each elem using the pretty printer provided by analysis into a list with the given separator (sep).

Optionally, it will break lines using the given character sequence (usually <br/>) and character limit.
