36.1 Shared And Read Only Strings

The procedures described in this section are deprecated because explicit shared substrings are planned to disappear from Guile.

Instead, all strings will be implemented using sharing internally, combined with a copy-on-write strategy. Once internal string sharing and copy-on-write have been implemented, it will be unnecessary to preserve the concept of read only strings.

• Shared Substrings: Strings which share memory with each other.
• Read Only Strings: Treating certain non-strings as strings.
