: For example:

: 	class chili {
: 	public:
: 		enum hotness { low=0, medium=500, high=1000, scary=10000 };
: 	};

So, a declaration like
	enum range{first=1, last=20};
permits
	for( range i=first; i<=last; i++)
		whatever;
An hence... (forgive my ignorance below):
	template <int first, int last> class range{
		enum{ FIRST=first, LAST=last }v;
	public:
		range(){v=FIRST;}
		range val(){return v}
		void reset(){v=FIRST;}
		bool ok(){return FIRST<=v && v<=LAST;}
		range& operator++{ v++; return *this;}
	...
	}

	for(range<0,17> i; ok(i); i++)

	for(range<0,32>chn; ok(chn); chn++)
	{ char c=char(chn);
	  whatever...
	}
