Certainly not with overloading.
Not a must have, in other cases using parentheses is cleaner.
Eliminating all that's redundant has the downside that recovery from syntax
errors is difficult, if not impossible. Typically, within each NT, you have
a set of delimiters where you can assume that some higher level NT
terminates (a closing bracket/brace/parenthesis) or enters another
subordinate NT (comma, semicolon).
Also, don't forget the help you get in an editor when you close a b/b/p by
highlighting the opening counterpart.
Architects have a name for this sort of thing, the German term is
"Orientierungsqualität", which could be translated as "guidance
quality".
Its lack in modern quarters is frequently appalling ;-)

Do you mean parentheses, i.e. ()?
How will a parser be able to determine the end of a parameterlist if there
is one call inside the other?
