Bug #8168: Feature request: support for (single) statement lambda syntax/definition
https://bugs.ruby-lang.org/issues/8168

ruby -v: ruby 1.9.3p392 (2013-02-22 revision 39386) [x86_64-darwin11.4.2]


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.
