Yes, sorry, I forgot to push fixes after merging. I included your fix for the 
switch case. Thanks.

They are just my experiments and I included them in tree-sitter.el as examples 
for anyone want to try out tree-sitter. They will be removed when tree-sitter 
integration merges into master. Each major mode should optionally take 
advantage of tree-sitter features according to tree-sitter-enable-p. (At least 
that’s my plan, no one has objected to this approach so far.)
