I agree.

The issue (for me) is not about "form" vs. "meaning". We all agree that 
each recognizer
(lexer, parser, treewalker) accepts things in a certain "form" and 
produces some sort of
data structure output that contains "meaning".

The issue (for me) is whether the term "syntax" is commonly used to 
refer to "form" for anything
(lexer, parser, or treewalker), or whether "syntax" just really refers 
to the "form" of a parser's
input. The "form" of a lexer's input is commonly referred to as 
something like "valid sequence of
characters". The "form" of a treewalker's input is just called an "AST".
