From: "garysweaver (Gary Weaver)" Date: 2013-04-12T04:11:58+09:00 Subject: [ruby-core:54192] [ruby-trunk - Feature #8168] Feature request: support for (single) statement lambda syntax/definition Issue #8168 has been updated by garysweaver (Gary Weaver). Oops except then they are symbols. Darn, too much to worry about... ---------------------------------------- Feature #8168: Feature request: support for (single) statement lambda syntax/definition https://bugs.ruby-lang.org/issues/8168#change-38469 Author: garysweaver (Gary Weaver) Status: Feedback Priority: Normal Assignee: matz (Yukihiro Matsumoto) Category: Target version: Abstract: Proposal for single statement lambda support, either via a new type of stab '->>', such that '->> some value;' would be equivalent to '-> {some value;}', or by just supplying a stab operator '->' with a value instead of a block (which would be more intuitive). Background: Often proc and lambda blocks are one statement long. Braces or do/end in this case are mostly unnecessary and result in less beautiful code Pros: may reduce amount of syntax required, especially if can re-use same operator. Cons: different stab operator may be confusing because of similarity to existing lambda operator. With either proposal, may cause additional overhead for interpreters. -- http://bugs.ruby-lang.org/
