Mutation-sharing substrings are only a minor additional semantical annoyance. They do enable new kinds of programs, and that makes them valuable. Also, there is the possibility on the horizon that we turn string-ref etc into 'primitive generics' which means that people could implement new kinds of strings using GOOPS. Also, I still like the idea of using mutation-sharing substrings as markers that allow O(1) access into variable-width encoded strings. -- GPG: D5D4E405 - 2F9B BCCC 8527 692A 04E3 331E FAF8 226A D5D4 E405 _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://mail.gnu.org/mailman/listinfo/guile-devel
