咳といいます。

助けてください。  
1.9のdRubyのretryのテストで困っています。

1.8で発生していたLocalJumpErrorが発生しなくなってしまい、  
dRubyでretryを捕まえられなくなりました。  
1.9ではどんな風にしたらよいでしょうか。

% cat retry.rb  
def test\_retry  
first = true  
block = Proc.new do |x|  
p x  
if first  
first = false  
retry  
end  
end  
[1].each do |x|  
block.call(x)  
end  
end

test\_retry

% ruby -v  
ruby 1.8.6 (2007-11-13 patchlevel 5000) [powerpc-darwin9.0.0]

% ruby retry.rb  
1  
retry.rb:7:in `call': retry from proc-closure (LocalJumpError) from retry.rb:11:in`test\_retry’  
from retry.rb:10:in `each' from retry.rb:10:in`test\_retry’  
from retry.rb:15

1.9では次のようになります‥

% ruby19 -v  
ruby 1.9.0 (2007-11-26 patchlevel 0) [powerpc-darwin9.1.0]  
% ruby19 retry.rb  
1
