Subject: [ruby-core:49299] [ruby-trunk - Feature #7346][Rejected] object(...) as syntax sugar for object.call(...)


Issue #7346 has been updated by matz (Yukihiro Matsumoto).

Status changed from Open to Rejected

I have once tried, but it caused serious incompatibility problem for example:

  p = Object.new
  p(15)

So compromise with object.() syntax introduced in 1.9.

Feature #7346: object(...) as syntax sugar for object.call(...)
https://bugs.ruby-lang.org/issues/7346#change-32857

Author: rosenfeld (Rodrigo Rosenfeld Rosas)
Status: Rejected
Priority: Normal
Assignee: matz (Yukihiro Matsumoto)
Category: core
Target version: Next Major


I propose for the parser to interpret "object(...)" as "object.call(...)". It should raise NoMethodError at runtime if object doesn't respond to "call".

This would read better than using "call":

double = -> n { n * 2 }

double(3) == 6

Sorry if this has already been proposed before (and rejected) but I couldn't find any references to something like this using Redmine's search interface.
