Py> print (x*x for x in range(10))
<generator object at 0x00AE71C0>

Oh, wait, this is what I actually meant:

Py> print " ".join(map(str, (x*x for x in range(10))))
0 1 4 9 16 25 36 49 64 81

Printing the contents of an arbitrary iterable is harder than it should be.
Many iterables (including the builtin ones) have a reasonable default display,
but a non-default display (e.g. linefeed separated instead of comma separated)
isn't the most obvious thing to express.

I thought making print a function solved that problem, but it doesn't really.
So I'm currently exploring a different approach involving string formatting.

Cheers,
Nick.
