Dear All,
Summary of the question:
Is it generally safe to dynamically change an objects class; if not
under which conditions can it be considered safe.
Context:
Given the code below, I have no direct control over Base and M1. M1
is a instantiated by 'calling' the read-only property of Base.

Are you aware of Python's own logging facility? It is quite powerful

For me it makes sense. operator.add should be used in a "global" context
(I don't know how to express it otherwise). So you provide it with the
two values that you want to add. The .__add__ variants are bound to a
particular instance and you provide it with a single value that you want
to add.

Hi,
Are you aware of the Python operator module?
It provides function equivalents of all (most?)
python operator. So instead of a==b, you can
state operator.eq(a,b). As a result, you can
loop over the key/value pairs in the dict and
built your logic with the operator.eq,
operator.and_, and operat

Hello,
You might want to take a look at:
sqlobject http://www.sqlobject.org/
or
sqlalchemy http://www.sqlalchemy.org/
Th
exported to FEA packages.
Another possibility is www.salome-platform.org which is build on top
of OpenCascade. It has
a nice Python interface which makes the learning curve probably a
little more acceptable. A
downside is that, I think there are no Windows binaries yet.

Marco Nawijn

forwarding each call in the Application class looks a little bit
redundant and I would like to get rid of it. Does anyone have any
comments or suggestions? Can metaclass programming come to rescue?
Kind regards,
