Bug #113: Complex(“1i”) clear $~  
[http://redmine.ruby-lang.org/issues/show/113](http://redmine.ruby-lang.org/issues/show/113)

同様に、Complex(“1i”) ã‚‚ $~ ã‚’ nil にするようです。

% ./ruby -e ’  
/a/ =~ “a”  
p $~  
p Complex(“1i”)  
p $~’  
#\<MatchData “a”\>  
Complex(0, 1)  
nil

## ちなみに Complex(“i”) は ArgumentError になってしまうので 1i としました。
