Test cases are still missing, so go crazy and try to break them! (The motivation for doing this now is that they make symbol->string efficient and we thus don't need an extra set of functions for converting symbols to C strings. Of course, they are a nice feature in general and much of the work needed for cow-strings is useful when properly supporting Unicode later.) >>From the NEWS: ** There is now support for copy-on-write substrings and mutation-sharing substrings. Two new procedures are related to this: substring/shared and substring/copy. See the manual for more information. _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://lists.gnu.org/mailman/listinfo/guile-devel
