Iterating over a file breaks line()

Try running this script. The first line is drawn, but the second line gives an error:

Traceback (most recent call last):
File "nodebox/gui/mac/__init__.pyo", line 358, in _execScript
File "/test.py", line 10, in
TypeError: 'str' object is not callable

This is on a fresh copy of 1.9.4.

stroke(0)
line(10, 10, 20, 20)
f = open("anyfile", "r")
for line in f:
    pass
f.close()
line(10, 10, 30, 30)

By "for line in f" you assign line to be a string, so its previous meaning gets overwritten, try "for l in f" or something like that.

Oh man I feel like a bonehead. Thanks :)
