Adopts new copyright and markdown toc checks. The new toc check generates the toc header, so that's why all the md files changed (this had felt better to me for the long-term, more auto-generated content)

TODO
This is a skeletal design, added to support the overview. It should not be treated as accepted by the core team; rather, it is a placeholder until we have more time to examine this detail. Please feel welcome to rewrite and update as appropriate.
Overview
The body or definition of a function is provided by a block of code containing statements, much like in C or C++. The body of a function is also a new, nested scope inside the function's scope (meaning that parameter names are available). Statements within a block are terminated by a semicolon. Each statement can, among other things, be an expression. Here is a trivial example of a function definition using a block of statements:
fn Foo() {
Bar();
Baz();
}
Statements can also themselves be a block of statements, which provide scopes and nesting:
fn Foo() {
Bar();
{
Baz();
}
}
