Hi Antonio!
just a few things that were not mentioned yet.
First of all: would you like to have your code live in the "official"
pypy-dist directory (Holger proposed using your user directory)? If
yes that would mean that you had to agree to license your code under
the MIT License (and to promise to follow the coding-guide and to
write tests :-). That would mean that much more people would see what
you are doing and could provide you with pointers about possible
improvements. The most appropriate place for a cli backend would
probably be pypy-dist/translator/cli

as I said I've begun writing the .NET CLI backend; it is still very
experimental but it can already compile correctly some code

very cool!
cool! I would be interested to hear a bit more about your concrete
current approach.
I respond here so that other can read, if they are interested.
The first decision I took is whether to generate IL code (to be
assembled with ilasm) or C# code: I choose the first mainly because
C# lacks the goto statement and it would be difficult to implement
flow control.

Will the .NET backend use the ootypesystem (which is what gensqueak uses)
it should use it but as it is, I think the ootypesystem is a bit too lax
type-wise, so the rtypeing of it can get away skipping casts (this is
mostly because so far its evolution has been driven
by gensqueak), basically the casts in ootype.py should not be noop but
switch between type-restricted views on the same object.
or the lltypesystem (which is what genllvm, genc and genjavascript
uses)? I guess for C# the former would make more sense, but I have no
clue how low-level IL is (I don't really have any clue about .NET at
all :-).
For simple things like arithmetic this is largely irrelevant but as
soon as it comes to any sort of data structure this is quite important.
Cheers,
Carl Friedrich
