Has anybody some experience in attaching comments, during parsing,
as attributes of an abstract syntax tree
(where and how attaching them)?
The parser is built using bison (or yacc).
The abstract syntax tree is built using rules such as:
                exp : exp KW_PLUS term
                    { $$=mk2(opplus,$1,$3) }
                    ;
                (here, the function mk2 builds a binary tree, the root of the tree
                  being the "operator" opplus)
