[Zope] Accessing module functions and variables

[Oscar Picasso]

Hi,

Is it possible, from isnside Zope,  to access to functions and variables that
are defined in a module used to create a Product?

I'm not speaking about external methods but a module that could be use for
example to also define classes.

I have seen register*Class for various classes in ProductContext, but nothing
specific for functions or variables.

Thanks
