hi all,

here comes a ArrayCtrl like grouper of Values to a ValueArray, returned as Value itself.
maybe its of help for someone..
since a variable arguments list is suboptimal in c++, this is definitely a better solution in general. good work who ever did this for ArrayCtrl..

syntax:

Value ToValueArray(const Value& [, const Value& ]...);

inline Value ToValueArray(const Vector<Value>& v)
{
	return ValueArray(Vector<Value>(v, 0));
}

inline Value ToValueArray(Vector<Value>& v)
{
	return ValueArray(v);
}

//$-Value ToValueArray(const Value& [, const Value& ]...);
#define  E__ToValueArray(I)      Value ToValueArray(__List##I(E__Value));
	__Expand(E__ToValueArray)
#undef   E__ToValueArray

#define E__Addv(I)    v << p##I
#define E__ToValueArrayF(I) \
Value ToValueArray(__List##I(E__Value)) { \
	Vector<Value> v; \
	__List##I(E__Addv); \
	return ValueArray(v); \
}
__Expand(E__ToValueArrayF)

CONSOLE_APP_MAIN
{
	Value v = ToValueArray(123, "Hallo", 23.0);
	RLOG(v);
}
