Block argument handling is inconsistent in 1.9 mode
---------------------------------------------------
Key: JRUBY-5997
URL: https://jira.codehaus.org/browse/JRUBY-5997
Project: JRuby
Issue Type: Bug
Environment: x86_64-darwin10.7.0
Reporter: Ilya Grigorik
Assignee: Thomas E Enebo
Fix For: JRuby 1.x+
Handling of passed in block params in --1.9 mode is different from MRI Ruby. In
1.8 (default) mode the behavior is as expected, but 1.9 is inconsistent (tested
with jruby-head, same behavior). Example:
<pre>
blk = Proc.new {|a,*b| p [:block_args, a,b] }
blk.call(1,2,3)
blk.call([1,2,3])
