Thanks.  Yuan, any comments, or should I install this?

I thought about an alternative: do something like that in
treesit-inspect-node-at-point, where the value of
treesit--inspect-name is computed, but perhaps we want to allow that
variable to be set by other Lisp programs (although it's an internal
variable)?
