Hi folks, The following paragraph appears in the new tutorial on interfaces:
The useful thing about value polymorphism is that it does not have to be static. If object-oriented languages only let you call a method on an object when they knew exactly which sub-type it had, that would not get you very far. To be able to call methods on types that aren't known at compile time, it is possible to specify 'bounds' for type parameters. Note the phrase "aren't known at compile time." That reads as if bounded types offer runtime polymorphism. (They don't, do they?)
