And because intellisense like features in an ide requires this

code_snippet :
 (
  LPAREN ()* RPAREN
 )
 | ~( ',' | RPAREN )
 )*

code_snippet_list! :
 code_snippet (COMMA code_snippet)*
 ;

CODE_SNIPPETS
 :
 LPAREN! (code_snippet_list)? RPAREN!
 ;

Im not sure that the ()* statement is correct
The scond lexer will feed in the define handler with any relevant char
Any comment is welcome !

handling #if #elseif #endif statement will be the final step here with c++
preprocessing .
