Thanks for responding @srowen. I have not used the Java API for Spark. But
if I understand what you said correctly, then yes, one of the uses for
`getOption` was to get `None`s where the value is `null`. However, I also
wanted exceptions to be converted to `None`s. I believe the use case is common
enough that we can have a method for it, instead of calling
`Try(getAs[Foo]("bar")).toOption` every time we want an `Option`al value. What
do you think?
