Still, for me distinguishing reference and value types seems to be 
artificial.

I learn OO in C++, where any type (both primitive and objects) can be 
passed both by reference or by value, depending on current needs.

So for me all this boxing and val/ref types seems to be nuisance.

Yes, I learn that objects in many languages are reference only... But 
still I find it inconvenient sometimes.
