Patrick Wendell commented on SPARK-2452:
----------------------------------------
I think we should narrow the description a bit. This is not a problem with all
compound statements, it's only a problem if a statement references a variable
within another statement.
{code}
// Reference
scala> val x = 10; val y = x + 10
x: Int = 10
y: Int = 20
scala> y
<console>:11: error: $VAL11 is already defined as value $VAL11
val $VAL11 = INSTANCE;
^
// Works fine
scala> val x = 10; val y = 20
x: Int = 10
y: Int = 20
scala> x
res3: Int = 10
scala> y
res4: Int = 20
