Issue #12902 has been reported by Aaron Lasseigne. ---------------------------------------- Feature #12902: How about Enumerable#sum uses initial value rather than 0 as default? https://bugs.ruby-lang.org/issues/12902 * Author: Aaron Lasseigne * Status: Open * Priority: Normal * Assignee: ---------------------------------------- In https://bugs.ruby-lang.org/issues/12217#note-3, Akira Tanaka, mentions that the default argument to sum is 0. This creates problems with non-numeric summations (e.g. strings). This would make the method more flexible. It also makes it behave more like `reduce`. I think using the initial value in the enumerable is less surprising than using 0. -- 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>
