An FnLikeNode is a Node that is like a fn, in that it has a decl and a body (as well as a NodeId, a span, etc).

More specifically, it is one of either:

• A function item,
• A closure expr (i.e. an ExprKind::Closure), or
• The default implementation for a trait method.

To construct one, use the Code::from_node function.
