I'm philosophically ok with "yet another formatting api" as in cfmt. The symbol argument list is an acceptable alternative to the keyword arguments. Could you edit the README.md to advertise...

could you post some performance benchmark?

From the way it is implemented, I'm not seeing what it offers materially either from a performance or expressiveness perspective. I recommend we reject this PR.

Should `README.md` be edited to say we don't need to free `xdoc` explicitly anymore? Are the examples in there canonical?
