[Chicago] is there really no built-in file/iter split() thing?

Bug: Eqivalent to f.read() if all your statements are on one line. ;)

I'd probably do something like this:

def chunker(f, sep=";", readsize=100):
    rest = ''
    while True:
        buf = f.read(readsize)
        if buf:
            chunks = (rest + buf).split(sep)
            for chunk in chunks[:-1]:
                yield chunk
            rest = chunks[-1]
        else:
            yield rest
            break
