Changing core to move from syntactic-based to semantics-based movement was brought up in another thread, concerning the meaning of ":" in ruby-mode: https://lists.gnu.org/archive/html/emacs-devel/2016-01/msg00125.html These are deep changes, with many implications, and I don't think we're rea= dy for that just yet. If we want to support a more semantic notion of what symbols and punctuations mean in various modes, we should think through all the ramifications, and come up with a design that either replaces or extends the current syntactic notions we use now. So I'm not in favor of making any code changes today; but I am interested in hearing proposals and ideas. =2D-=20 John Wiegley GPG fingerprint =3D 4710 CF98 AF9B 327B B80F http://newartisans.com 60E1 46C4 BD1A 7AC1 4BA2 --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQGcBAEBCgAGBQJWlTlgAAoJEMFE2PTxn+YwWo8MANMlTPSk2AQQBspwxlWt6nZ8 e0vKEiwEh2Eei4wV0hqtaXvSveHdwFHnETkJqCg/max/LQkOvKuD7J5kxw150aeo cgu73Q4ElzGCHSNTHXxKhqd3CQn+3atShP95D8fiB7SSmzvW/6PBQqK7u0uUitOn jsl5l8EpeX7EJxvuqRfhlm/1eG7K1e7nKn3npWKOrfIhs70GA9Cctcs6QN6FyvVM kIxrUW2ajzjP9JVybHic6OGTFw/P7Nk53M0ChJPQS8xXt/mv4s6vKtBjSNHJuBjo NPUqT+BhbmAhQiuWp8rOpLc5Krvy4zRNXWPGdXTZmJryT6Rv+3QZbZzGyvQG8wu7 oZshmJ+EAgrotiMWcNy8pvcAmDrq5Bv2IWfWcQElJ4uEpc/UkmQRyVWYmS5m5/TU azE3Mft2Vzq4KOuEewf/pH54m2SkKZQZiXycr14VpI6wVrbhtW4ATSu+Crc+k2D4 zl1HyFlRYqLYOx/t7ol1Gm5HBztiecUcwi0u6hyXYQ== =u5Rn -----END PGP SIGNATURE----- --=-=-=--
