[Jython-dev] Hi

[Ruchir T. <ruc...@gm...>]

Hi,
Im an avid Jython developer and have been following this dev list for some
time.
I have a question about Jython which has bothered me for some time and I
don't know who to ask.
It does not belong to the users list because I know it is not possible at
the moment.


class A(object): pass
A=A()                        # Ive lost class A
b=A()
Traceback (innermost last):
  File "<console>", line 1, in ?
TypeError: call of non-function ('__main__.A' object)

How do I protect 'A' ?
Can we not provide a hook when binding a variable to an object in the
locals(), globals()

something like __localbind__(), __globalbind__()

I saw some post somewhere which said it is not possible in Python and that
it really isn't something to be concerned about?

Im currently developing a framework in Jython using PyServlet to load
different web servlets.
In those servlets I want to be able to make available certain of my own
datatypes e.g. MO (money), LD (Large decimal) etc
The problem is that these types can be easily overwritten in the current
namespace.

I don't think this is a small issue and im definitely concerned about
failing servlets etc. because a programmer has typed it wrong!

I would like to propose that a hook be given to the programmer so that this
is not overwritten.

Im sorry if this question does not belong here. Please bear with me and do
tell me where i should post it if not here?


Thanks
Ruchir
