Incorrect argument splatting/array construction passing splatted args through a
block that yields
-------------------------------------------------------------------------------------------------
Key: JRUBY-2801
URL: http://jira.codehaus.org/browse/JRUBY-2801
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Reporter: Charles Oliver Nutter
Fix For: JRuby 1.1.3
This doesn't appear to be specific to compiler or interpreter, so it's either
an issue with blocks in general or something specific to
Enumerable#each_with_index:
{noformat}
class Proxy
def initialize(target)
@target = target
end
private
def method_missing(method, *args)
if block_given?
@target.send(method, *args) { |*block_args| yield(*block_args) }
else
@target.send(method, *args)
end
end
end
a = [1, 2, 3]
Proxy.new(a).each_with_index {|x,i| puts "#{i}: #{x.inspect}"}
{noformat}
Output on JRuby and Ruby:
{noformat}
