Hi guys,

I was on the way of running RSpec in IronRuby. After some hacks I was  
able  
to run basic specs. However I came up to a problem that “before :each”  
was  
not called in IronRuby. After some digging I was able to find the  
problem.  
Here is a small repro:

module M  
end

class MyClass  
extend M  
end

MyClass.kind\_of?(M) # returns true in IRB, but false in IronRuby

Regards,  
Stefan

Nice catch, can you post this as a bug on the rubyforge?

Thanks,

JD
