Ur rgiht with the grammar... 
There are

• Operators{...}
• $Keywords
• Locals
• Iterators{[Merger] ...}

Have a look at QEDS...

There each node (vertex/face) has Properties/Operators/Iterators seen in the picture above. 
Beside there is a local Key-Value-Database (Key=string, Value=GH_Variant) assigned to them prior. 

Getting them is as simple as using the key as a variable in an expression. 
The locals are going to be parsed (finaly) by the gh-internal parser and set as variables.

Have a look at this example.

Can you explain what is behind this? It seems to assign behavioral instructions to mesh vertices using your own grammar, is that correct? In that case, it would be good to include custom attributes to the vertices, like $Attribute[index] or $Attribute["name"].
