Issue #18597 has been updated by Dan0042 (Daniel DeLorme). Please give a concrete example of code that would benefit from such a method. ---------------------------------------- Feature #18597: Strings need a named method like `dup` that doesn't duplicate if receiver is mutable https://bugs.ruby-lang.org/issues/18597#change-96619 * Author: danh337 (Dan H) * Status: Open * Priority: Normal ---------------------------------------- This is related to #16295, but focuses only on the `.+@` part. Currently we can use `.dup` in a method chain when we need to mutate a String. However there are cases where the code's context *expects* the String to be mutated. In cases like this, `.dup` always works, but we don't want to duplicate a String that is already mutable. Since `.+@` looks more like an operator, it can be unintuitive in a method chain, so this is asking for a new named method that can be used in its place, instead of always `.dup`. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
