Hi Eric. I did mention that option in my report, but that option requires loading the whole file into memory. I'd like something equivalent to the iterator that `open()` provides, which yields lines lazily.
Serihy, thanks for the feedback. I do indeed not want to rely on the implicit closing of the file handle. I'd instead like a helper function/method that will close the file after the iterator is consumed.
Something like:
def read_lines(path):
with path.open() as strm:
yield from strm
What I'm seeking is for that block to be placed somewhere in the stdlib so that I don't have to copy it into every project that needs/wants this behavior.
