This is how I'm interpreting discussion:
- Basic elements are getting set to an ID.
- SetName exists to assign a name (which can then be referred to later with an identifier expression) to an ID.
- Expressions are broken down into a series of operations which operate on IDs.
So with something like the last test:
```
fn Main() { return 12 + 34; }
```
This becomes:
```
Function(%0,
{IntegerLiteral(%3, 12),
IntegerLiteral(%2, 34),
BinaryOperator(%1, +, %3, %2),
Return(%1),
})
SetName(`Main`, %0)
```
Note I'm treating blocks as fairly equal to the top of a file now, and basically eliminating boundaries between things. That's because we have discussed also supporting code like:
```
fn Foo() {
fn Bar() {}
Bar();
}
```
Here a declaration of a function is occurring inside a code block, so it felt like eliminating the difference was the best choice.
I know you'd commented on the separation of nodes to individual files before; I still think we're going to have a lot of different types of nodes, and so separating them out into individual files makes them easier to browse.
