Yes, if it were c, you'd need the lr stuff, I guess.

But just parenthesized expressions and function calls,
isn't that basically dead simple?  Recursive descent
or the like.  And so unlike an lr scheme, with 
recursive descent the parsing code is readable and
understandable.  (Once someone does the first and
follow sets -- sort of beyond me!)
