Enumerable does not splat
-------------------------
Key: JRUBY-6171
URL: https://jira.codehaus.org/browse/JRUBY-6171
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.6.5, JRuby 1.6.4
Environment: jruby 1.6.4 (ruby-1.9.2-p136) (2011-08-23 17ea768)
(OpenJDK Client VM 1.7.0-ea) [darwin-i386-java]
Reporter: Theo Hultberg
Assignee: Thomas E Enebo
It seems like Enumerable changed its behaviour between 1.6.3 and 1.6.4, it no
longer splats the yielded arguments:
Running this code in 1.6.3:
{noformat}
x = Enumerator.new do |y|
('a'..'z').each do |letter|
y << [letter, letter.upcase]
end
end
x.each do |downcased, upcased|
puts %(#{downcased.inspect} #{upcased.inspect})
end
{noformat}
gives the following output:
{noformat}
"a" "A"
"b" "B"
"c" "C"
"d" "D"
"e" "E"
...
{noformat}
which is the same as MRI 1.9.2 gives, however, in 1.6.4 this is what is printed:
{noformat}
["a", "A"] nil
["b", "B"] nil
["c", "C"] nil
["d", "D"] nil
["e", "E"] nil
...
{noformat}
The first argument to the block contains the array, instead of splatting it
across all the arguments to the block.
