### new-nu-parser integration notes

I am going to write my questions down here but they are mostly for me to better understand things prior to asking JT and Stefan. So far I am understanding the new parser.

### Comparison of the new AstNode versus the old

| New | Old |
| -------- | -------- |
| AstNode::Int | Expr::Int |
| AstNode::Float | Expr::Float |
| AstNode::Equal | Comparison::Equal |
| AstNode::NotEqual | Comparison::NotEqual |
| AstNode::Plus | Math::Plus |
| AstNode::Minus | Math::Minus |

I like the new design better with one less level of indirection !
