Struct collect_upvars

pub struct collect_upvars;

builtin! fn collect_upvars (ConValue::Function(f)) -> IResult<ConValue>
{
    use crate::function::collect_upvars::collect_upvars; for (name, bind) in
    collect_upvars(f.decl(), env)
    {
        match bind
        {
            Some(bind) =>println!("{name}: {bind}"), None =>
            println!("{name}: _"),

    } Ok(ConValue::Empty)
}
