def _until_eof(stream):
while True:<EOL><INDENT>line = stream.readline()<EOL>if line == '<STR_LIT>':<EOL><INDENT>break<EOL><DEDENT>yield line<EOL><DEDENT>
Yield lines from an open file. Iterating over `sys.stdin` continues after EOF marker. This is annoying, since it means having to type ``^D`` twice to stop. Wrap this function around the stream to stop at the first EOF marker.
