I should have a fix in for __init__ and __call__ later today.  (Issue #20294.)
For the record, you could convert them, you just had to wrap the parsing function
to deal with the return type difference, and *args / **kwargs might be tricky too.

In the next few days I'm going to add support for "*args" and "**kwargs", and
then you'll be able to convert these functions.  (Issue #20291.)  Again, even
if Argument Clinic doesn't do any parsing, it's still helpful to have it
generate signatures.

You'll be able to do this soon:

parameter: object(c_default='pysqlite_PrepareProtocolType') = ProtocolType

This feature isn't checked in yet, I'm waiting for a review.  It's part of
#20226, which I guess you already noticed.

You can't.  How about you use a default of -1 and then:

  if (maxrows == -1)
      maxrows = self->arraysize

I'd prefer it if you converted them anyway.  Converting them means they'll
have signature information which is an unconditional good.

Once I add the ability to pass in *args and **kwargs, you'll be able to
convert sqlite.connect.  

I think I responded to all your other comments when I reviewed the patch.

Thanks!
