Can you try
```d
template getParams(alias overload) {
   static if (__traits(isTemplate, overload)) {
     //alias typed = overload!int // error: fun(...) matches more 
than one template declaration
     alias getParams = Parameters!(overload!int); //don't use 
alias, send the argument directly
   }
}
```
