override def transformAssign(tree: Assign)(using Context): Tree

If assignment is to a boxed ref type, e.g.

If assignment is to a boxed ref type, e.g.

intRef.elem = expr

rewrite using a temporary var to

val ev$n = expr
intRef.elem = ev$n

That way, we avoid the problem that expr might contain a try that would run on a non-empty stack (which is illegal under JVM rules). Note that LiftTry has already run before, so such trys would not be eliminated.

If the ref type lhs is followed by a cast (can be an artifact of nested translation), drop the cast.

If the ref type is ObjectRef or VolatileObjectRef, immediately assign null to the temporary to make the underlying target of the reference available for garbage collection. Nullification is omitted if the expr is already null.

var ev$n: RHS = expr
objRef.elem = ev$n
ev$n = null.asInstanceOf[RHS]
