[ruby-core:59694] [ruby-trunk - Feature #8168] Feature request: support for (single) statement lambda syntax/definition

Issue #8168 has been updated by Alexey Muranov.


I do not understand the argument about the code presumably looking ugly with curly braces (maybe if code looks ugly, it is better to read poetry? :)).

I do not think that

    foo ->> Time.now

is more beautiful or clear than

    foo lambda{ Time.now }

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.
