It's the basis of static if - does this piece of code compile. It's been a rich 
source of bugs because if the compilation fails, it can leave the state of the 
compiler in an indeterminate state.

Yes.

Yes. Mere translation would not change the license.

But I view the backend license encumbrance as more of a theoretical issue than a 
practical one - the license is extremely permissive. There isn't that much more 
to it than agreeing to not sue Symantec.
