heredoc is lost when parsing into syntax::List

[kpcyrd]

hi!

I have a program like this:

use yash_syntax::syntax;

fn main() {
    let script = r#"
echo 123
cat 1>&2 <<EOF
this is lost
EOF
echo 'but
multiple
lines
work'
"#; 
    let parsed: syntax::List = script
        .parse().unwrap();
    println!("{}", parsed);
}

and executing it gives me this output:

echo 123; cat 1>&2 <<EOF; echo 'but
multiple
lines
work'

the heredoc is lost and the shell code is semi-invalid, it still executes but gives a warning/error:

sh: line 4: warning: here-document at line 4 delimited by end-of-file (wanted `EOF')
123
but
multiple
lines
work

Is there a way to preserve the heredoc?

Thank you for making this crate!

Actually the here-doc is lost not when parsing, but when printing.
Unfortunately I have to say the Display implementation of the yash_syntax crate does not yet support printing here-docs. I intend to implement it, but it won't be very soon.
