... for uninitialized variable values Check for memory leaks Check for null pointer dereference When you index into an array, in Java it takes some method call in the virtual machine, bound checking and other sanity checks. That is valid and absolutely fine, because it adds safety where it's due. But ...

... to blatantly disregard that for the sake of simplicity. A few initial points: Note that "union" is probably not the best term for A+B here--that's specifically a disjoint union of the two types, because the two sides are distinguished even if their types are the same. For what it's worth, the m...

...ntime another compiler called the JIT (Just In Time) compiler turns the IL into actual machine code that can execute. So first let's answer the question "why have MSIL at all?" Why not just have the C# compiler write out machine code? Because it is cheaper to do it this way. Suppose we didn't do...
