Short description of the scoping rules?
...file, but other parts of file still use the print statement. In Python 2.6-2.7 you can get hold of the Python 3 print function with:

What is a “context bound” in Scala?
... function f on a range of numbers from 0 until a given length. Up to Scala 2.7, tabulate could be
written as follows:
def tabulate[T](len: Int, f: Int => T) = {

}
In Scala 2.8 this is no longer possible, because r...
