Ok for pypi. (I've never tried to make python C extension, I feel it's going to be epic :) )

@Oleg

you can override default behaviour with __ducktypecheck__

it's not as strict as an interface as var names can be differents and can have defaults.

then instead of declaring an interface with "read" and "write", you just create a base class with these methods.

What solution do you suggest ?

I've made a function that returns public members only, maybe this method can be exposed in the api too.

Isn't the requirement too strong? When I need a file-like object I
seldom need more than .read() and .write() methods, and even of those I
seldom need both at once -- I usually need one or the other.
Testing for strict conformance is not duck typing IMO -- it's
interface.

Programmers don't die, they just GOSUB without RETURN.
