That particular case is handled by the built-in (but cunningly
concealed) 'excel-tab' clas
for row in csv.reader(instream, delimiter="\t"):
Awesome. Thanks.

The csv.Dialect class is essentially pure abstract. Most of the time I
subclass csv.excel and just change the one or two things I need.

The docs clearly state what the defaults are, but they are not
in the code. It seems so clumsy to have to specify every one
of these, just to change the delim

Ok, I'm an idiot. I didn't even pass my dialect
object to the reader() call.
So now it works, but it is still strange about
the absent defaults.

I'm trying to create a cvs.reader object using a custom dialect.
The docs are a little terse, but I gather that I am supposed
to subclass cvs.Dialect:
class dialect(csv.Dialect):
pass
Now, the docs say that all of the attributes have reasonable
defaults, but instantiating the above gives
