Because explicit is better than implicit. Returning a "file-like" object
can mean, "read all the data and send it as one block", or "read the data
in arbitrary-size blocks and send them". The application should say what
it means! Either:
return iter(lambda: filelike.read(bufsize), '')
or something else, according to the results it intends. The server
shouldn't have to *guess* which of these is meant.
