REPL caching?

Hey all!

Recently I started using JRebel with the Scala REPL and came across
some strange behavior. For example, consider the following workflow.
One explanation is that the REPL caches members of a class, which can
get out of sync with the class if the class changes.

emacs test.scala
# Create an object Test with a function foo
object Test {
def foo: String = "bar"
}

scalac test.scala

scala
scala> Test.foo
res0: String = bar

# Now I go and add a new function to Test

emacs test.scala
# Create an object Test with functions foo and bar
object Test {
def foo: String = "bar"
def bar: String = "foo"
}

scalac test.scala

# In the same REPL, I now reload the class using JRebel
# When I list all the declared methods on Test, I see bar
scala> Test.getClass.getDeclaredMethods
res8: Array[java.lang.reflect.Method] = Array(public java.lang.String
Test$.foo(), public java.lang.String Test$.bar())

# However, the REPL doesn't
scala> Test.bar
:40: error: value bar is not a member of object Test
Test.bar
