Naming conflict with main function in main.vi file

[nilscrm]

Given the file main.vi with

pub fn main(&io: &IO) { }

the following error occurs:

error main.vi:1:1 - duplicate definition of `main`
error - cannot find `main` in `::main`

This is because the ::main::main function definition clashes with the internal ::main node that is used as entry point to the program.
