From: aaron.lasseigne@... Date: 2016-11-04T19:28:28+00:00 Subject: [ruby-core:77931] [Ruby trunk Feature#12902] How about Enumerable#sum uses initial value rather than 0 as default? Issue #12902 has been updated by Aaron Lasseigne. 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). I would like to suggest using the first enumerable value. 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. ** I missed a sentence. :( ** ---------------------------------------- Feature #12902: How about Enumerable#sum uses initial value rather than 0 as default? https://bugs.ruby-lang.org/issues/12902#change-61244 * 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.
