Double representation

Basics

Each node in a Luna graph corresponds to a line of Luna code. For example:

a = 1
b = 2
c = a + b
c.succ

Let's break this graph down:

1. The two leftmost nodes correspond to the lines a = 1 and b = 2. The variable names a and b become names of their corresponding nodes, and the numbers 1 and 2 are their definitions. They have no input ports and one output port each.
2. The node in the middle corresponds to the line c = a + b. It has the a and b nodes connected to its inputs. Thanks to this, you can clearly see where does the input data come from.
3. The rightmost node corresponds to the line c.succ. The node has no name, as the corresponding line does not define any variables. It has the node c connected to its self port. This port denotes the target of method call (more on different port types later).
