That seems to be working rather well, thanks. I just needed to extend 
the list of nodes:

  (setq-local treesit-sexp-type-regexp
              (regexp-opt '("class"
                            "module"
                            "method"
                            "argument_list"
                            "array"
                            "hash"
                            "parenthesized_statements"
                            "if"
                            "case"
                            "block"
                            "do_block"
                            "begin")))

With array, hash, etc, you see it's not exactly like a sentence.

Regarding your previous question -- whether forward-sexp should jump 
over the arglist together with the called method name -- ruby-mode's 
answer to that is:

- If point is before ".", jump over ".bar(...)".
- If point is after ".", jump over "bar" only.

But the difference is more subtle here, and different people might have 
different preferences. This also seems more difficult to express via 
node types since "." is in the middle of the (call) node.
