note that the standard pydiom (the while 1 loop) is
a refactored version of the old read-ahead pattern,
with a couple of extra advantages:

+ no code duplication

+ no need to use nested if statements to skip lines or
  records; a plain continue all that's needed to get to
  the next line/record.

    while 1:

        line = fetchline()
        if end of data:
            break

        if empty:
            continue
        if comment:
            continue

        process line
