Pub

By default all code in a file is private to that file. One could think of it as being inside an anonymous namespace.

The pub pragma publishes the code identified by the name to be used by other code files / modules.

The following types of identifiers can be public:

• Types
• Functions
• Immutable Variables

Mutable variables cannot be public! They need an accessor function.

Here is an example of making a function public:

#pub MyFunction
// -or-
#pub
    MyFunction
    // more functions here...

MyFunction: ()
    ...

The pub pragma can also be applied directly to the code identifier to be made publicly available:

#pub MyFunction: ()
    ...

How we make clear(er) this is not a compile-time function?

Aliasing

By using an alias the name of the public item can be renamed to something new. It can also be a way to simulate namespaces.

#module alias_example
#pub MyNamespace.MyFunc = MyFunc

MyFunc: ()
    ...

#use alias_example

MyNamespace.MyFunc()

TBD: This can conflict with module names with namespaces. Drop this?
