Eregon (Benoit Daloze) wrote: > Yes, I think it's a possibility and is rather consistent. Agreed, it is the most consistent. IMHO, `p (1..) #=> 1..nil` is a bit verbose, though. I think that an endless range will be much more commonly used than a beginless one because an endless range has many use cases but a beginless range has only one use case (DSL-like usage). Thus, I liked to make an endless one more useful and implemented the current behavior. But I admit that the current behavior looks inconsistent. I have no strong opinion. I'll hear other committers' opinions at the next dev meeting. ---------------------------------------- Bug #15745: There is no symmetry in the beginless range and the endless range using `Range#inspect` https://bugs.ruby-lang.org/issues/15745#change-77809 * Author: koic (Koichi ITO) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.7.0dev (2019-04-03 trunk 67423) [x86_64-darwin17] * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- The following commit introduces beginless range. https://github.com/ruby/ruby/commit/95f7992b89efd35de6b28ac095c4d3477019c583 ``` % ruby -v ruby 2.7.0dev (2019-04-03 trunk 67423) [x86_64-darwin17] ``` There is no symmetry with endless range when using `Range#inspect` method. ``` (1..).inspect # => "1.."
