Allow the addition of functions and variables

[jamesvega]

Hello,
Modules automatically create a namespace for their contents. As a 
result, you cannot define a function in a module with a different 
name, which doesn’t seem ideal to me.

For instance, I developed a library for creating application 
plugins. I want to prevent users of my library from overriding 
certain abstraction functions (like DLLMain on Windows) and 
encourage them to define their own plugin launch functions as 
examples.

It would be beneficial to allow the addition of functions and 
variables that are independent of any specific module.
