[antlr-interest] This should be simple, but I can't find the right syntax (or is it a bug?)

It turns out that it was a known bug. Thanks to Maik Schmidt for pointing me to the fix. It worked.

Try this and see if it makes any difference.

<vals: {<it>}; separator="\n">


Also, is the rule borg definitely returning a template?
