Hi,
Recently, I got a request [1] to support pickling of
`FTPHost` instances in my `ftplib` library.
I explained in the ticket why I think it's a bad idea and
now want to make explicit that `FTPHost` objects can't be
pickled. The usual way to do this seems to be defining a
`__getstate__` method a

Hello,
I'm currently changing the FTP client library ftputil [1]
so that the same code of the library works with Python
2 (2.6 and up) and Python 3. (At the moment the code is for
Python 2 only.) I've run into a API design issue where I
don't know which API I should offer ftputil users under
Pytho
ut in my reader I
only saw one answer in the newsgroup.)

Hello,
I wrote a `Connection` class that can be found at [1]. A
`Connection` object has a method `put_bytes(data)` which
returns a "future" [2]. The data will be sent asynchronously
by a thread attached to the connection object.
The future object returned by `put_bytes` has a `was_sent`

If you consider strings, only an empty string has a false

a true boolean value.
