Here is the real app code which I tried to mimic
switch (ntoken) {
case Token.CLOSE_PARENS:
ntoken = xtoken ();
//
// Token is a lambda
//
if (ntoken == Token.ARROW) {
if (RootContext.Version <=
LanguageVersion.ISO_2)
Report.FeatureIsNotAvailable (Location, "lambda expressions");
return
Token.OPEN_PARENS_LAMBDA;
}
//
// Token is possible cast, parser will
decide later
//
if (cast_posible && !cast_not) {
switch (ntoken) {
//
// Indirection is a special
// cast: (int*)&a;
// binary: (C)&a;
//
case Token.BITWISE_AND:
case Token.OP_INC:

break;
