* This is just before methods started to be moved from Ruby code to the C extension. * BTW, in the ruby/pathname repository there was no pathname.rb before that commit.
* This means it's only additions in lib/pathname.rb and zero removals.
* The <=> implementation in the extension is much faster, so is kept. * The other methods are actually faster in Ruby than in C, because rb_funcall() and rb_ivar_get() in C code have no inline cache, but method calls and `@path` have inline caches in Ruby code. https://railsatscale.com/2023-08-29-ruby-outperforms-c/ is an explanation of that (though it was known well before that).
* Avoids a MatchData allocation.
By doing most of `<=>` can be implemented in Ruby, it's really only the path comparison that benefit from C.
