Explicit initialization function for modules

[sameerajayasoma]

Should we allow developers to declare an explicit module init function? The module init function can be used to initialize module-level variables. Sometimes it is hard to initialize them in the initializer expression. Another use case would be to initialize the final variables conditionally.

I think this would be a useful feature to add a some point. Is the function called init like main or __init like an object initializer?

[sameerajayasoma]

I think we should make this __int, because it is similar to the object initializer. It is a function with module-level visibility which cannot be called by the module code.

+1.

Return value would need to be subtype of error? like __init on objects. Must not have public visibility
