I would agree with that it makes no sense that it's an 
AssignExpression.

It would've made more sense if the normal if statement was an 
AssignExpression, but even that isn't.

I don't believe there are any situations where you'd end up with 
an AssignExpression as the condition for a static if statement.

Either there is a magic reason for some compiler bug that it 
avoids OR it's a simple mistake.
