You can write a simple paste() function. For example:

    import sys
    paste = lambda: exec(sys.stdin.read(), globals())

    >>> paste()
    class Foo:
        """test class"""

        def spam(self):
            '''test method'''
            return 'eggs'

    >>> Foo().spam()
    'eggs'

In a Unix terminal and IDLE, stdin.read() is terminated by typing
Ctrl+D at the start of an empty line. For the Windows console, it's
Ctrl+Z, Enter. Actually in a Unix terminal the cursor can also be at
the end of a line, but a bug in Python requires pressing Ctrl+D twice
in that case.
