All Oberon implementations I am aware of allow the nesting of comments,
but they do no "lexing" of the contents of comments.


In the scanner, there is a procedure that "consumes" the comment; if
you come accros another start comment ("(*" in Oberon), recursively call
this procedure again. It would be simple to extend the procedure in
order to take care of start/end comments in strings.
