Thanks.  I believe the plan is to use Tree-sitter for the jobs for
which a parser is needed.  But we also want to have an API that could
accommodate other parsers into the same framework.  So I think it
would be good if you cooperate with Yuan Fu <casouri@gmail.com>, who
is working on Tree-sitter integration, so that the API for using a
parser could be a common one.
