Simplified package declaration for the Main package #2550

Merged

@zygoloid zygoloid commented Jan 24, 2023

Make the preamble of simple programs more ergonomic, by removing the
package Main from the main package and removing the package declaration
entirely from the main source file. Imports within a single package no longer
need to, and are not permitted to, specify the package name.

Partially covers #2001 / #1136.
Covers #1869.
Supersedes #2265.
Addresses design idea #2323.

To the extent that this proposal is renaming the entry point from Run to Main in documentation, would it be good to try resolving #2265 first? It looks like that proposal has been quiet for a couple months, and could maybe use attention from leads.

Mostly marking this as needing an update now that #1869 is sorted out. Also a small comment inline.

I think this proposal is in a good state, regardless of how my pedantic comment is resolved.
