Is there any reason why we don't already have this?

```d
template foo(T...){
   static switch(T){
     case(int I,string S){
        foo()=>iota(0,I).each!(()=>s.writeln);
     }
     case(S:int){
        foo(int i)=>i.writeln;
     }
     case(S) if(isNumberic!S){
        foo(S i)=>i.writeln("not int");
}}

unittest{
   foo!(10,"foo");
   foo!int(10);
   foo(13.37);//inferred somehow
}
```
