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)

I just let it run on TIO, and it outputted two of the lines switched. You can easily fix that without changing the length by replacing & with ; which removes the concurrency.
