public class StreamCallSymbol extends MethodSymbol
Just re-uses the bulk of method symbol. This is only used in part of the stream pipeline. We need additional information surrounding the type that can be accepted and the type that is produced (chained). In some cases (like a call to head) we can accept anything in and will produce the same back out. But a filter can only accept a certain type in - but will then also product that same type out. A map on the other hand will only accept a certain type and will product another type (maybe - depending on the map). Flatten can only accept something is can iterate over and will then product whatever that type is that is provided by the iterator. This is the 'glue' between streaming commands and functions.
