Looping counter

Create an infinite loop that outputs lines of asterisks, with each line containing one more asterisk. Instead of the asterisk, any printable, non-whitespace character can be used. However all lines need to use the same character.

The beginning of the output looks like this:

*
**
***
****
*****
******
*******
********
*********
**********
***********
************

An ungolfed Python implementation:

from itertools import count

for i in count(1):
    print('*'*i)

This approach also works in 3.x, if parentheses are added to the print usage - of course, this only ties the result from the simpler-to-understand approach, while that approach would waste a byte here (due to the need to separate _ from print).
