This written as a static foreach or declarative foreach, would be 
awesome if it exposed the scope. For now the only solution is to build a 
string and mixin the string like this

string fct(R)(){
	string str;
	foreach (range ; R)
		str ~= "int num " ~ range.stringof ~ ";";

	return str;
}

mixin(fct!(TypeTuple!(1,2,3));
writeln(num1,num2, num3);

Looks a little less convenient than

static foreach ( i; 0..3 )
	mixin("int num" ~ i.stringof ~ ";");
writeln(num1,num2, num3);
