Ah... I see...you're casually referring to AST structure as "syntax" to 
give Terrence something convenient to site
and show that he's not the only one who uses the word "syntax" that way ;)

Sorry, that doesn't count ;)
No retroactive immunity allowed.
You're just confusing people by referring to AST structure as 
"surrounding syntax" and "internal syntax".
Better to stick with the tried-and-true "tree structure" nomenclature.
