[ruby-core:63835] [ruby-trunk - Feature #10064] [Open] &:symbol in when clause

Issue #10064 has been reported by Kenta Murata.
----------------------------------------
Feature #10064: &:symbol in when clause
https://bugs.ruby-lang.org/issues/10064
* Author: Kenta Murata
* Status: Open
* Priority: Normal
* Assignee: Yukihiro Matsumoto
* Category: syntax
* Target version: current: 2.2.0
----------------------------------------
Now we can put Proc objects in a when clause as this code.
~~~
require 'prime'
def test(n)
print "#{n} is "
case n
when :zero?.to_proc
puts 'zero'
when :even?.to_proc
puts 'an even number'
when :prime?.to_proc
puts 'a prime number'
else
puts 'a non-prime odd number'
end
end
(1..10).each &method(:test)
~~~
I would like to write it as below:
~~~
require 'prime'
def test(n)
print "#{n} is "
case n
when &:zero?
puts 'zero'
when &:even?
puts 'an even number'
when &:prime?
puts 'a prime number'
else
puts 'a non-prime odd number'
end
end
(1..10).each &method(:test)
~~~
How do you think about this new syntax, Matz?
