When I tried some examples out on cfront last year, it accepted only
initializers of the form "( expression-list )".  The grammar in the book
is a simplified guide for programming, and has a number of ambiguities
more subtle than those resolved by the precedence of operators.  Stroustrup
acknowledges the book's inadequacy in defining C++.  A real language
definition is in the works.
