Tutorial 'Generic Type' example fails to compile to extension module

[GoogleCodeExporter]

What steps will reproduce the problem?
Generic Type example ( in the readme.html ) does not compile to an
extension module

What is the expected output? What do you see instead?
I'm guessing it should spit out a pyd, but instead I get:

It compiles fine to an exe. Code is below for convenience

class matrix:
    def __init__(self, hop):
        self.unit = hop

m1 = matrix([1])
m2 = matrix([1.0])

hope it is helpful :)

What version of the product are you using? On what operating system?
SS 0.1, WinXP 32-bit

hi benjamin,

thanks for reporting! I put this on my TODO list to investigate. it's probably 
a bit
complicated to export generic types in extension modules, but they should 
compile at
least, and in such a way that you can still use the non-generic parts.. 
(especially
if the code is mentioned in the tutorial of course! ;))

okay,

I made thing degrade gracefully in the face of generic types/functions, so they 
are
simply not exported now. this is about as far as I'd like to go for now..

thanks again for reporting.
