that's all fine if so long as you're inside your Map class.

not so fine if all you'ev got is a list and want to do stuff like this

def myList ; List[Product] 

myList.map { each -> print (each) } 

print "total price =   sum(myList.map{ each -> each.price }) 

without having to write the result of type the block each time,
and without having to give up type checking
