Hello,

I get very odd results with attached code:

* * *

#System::Windows::Forms::Form:0x000005c  
nil  
#System::Windows::Forms::Form:0x000005e

* * *

While was expected

* * *

#System::Windows::Forms::Form:0x000005c  
#System::Windows::Forms::Form:0x000005c  
#System::Windows::Forms::Form:0x000005e

* * *

The ‘nil’ is printed by this expression:  
form = form.test

and the test method definition is:

class Object  
def test  
p self  
end  
end

The hint: ‘form’ variable was set by the script host (SetVariable).

I am using DLR-0.9.

Thanks,

- Alex
