RA

• ra do not have a TokenStream object
• ra do not have a SyntaxExtension object
  • SyntaxExtension is a rustc enum, representing the different kinds of syntax extensions.
  • link
• The current parser implementation about MacroCall:
  • When it see a MACRO_CALL, it just bump all lexer's SyntaxKind to rowan and build a rowan::SyntaxNode
  • Although we have a tt::TokenTree (not confused with syntax::TokenTree), we only generate it during macro parsing and expansion.
