Thank you for your suggestion.
For the record, the code below behaves as expected.
```
void main() {

    int  VarInt;
    int* VarIntPtr;
    double VarDbl;

    do_something!VarInt;
    do_something!VarIntPtr;
    do_something!VarDbl;
}

void do_something(alias v)() {

    import std.stdio;

    if (typeof(v).stringof == "int" ) {

       writeln("int var detected");
    } else if (typeof(v).stringof == "int*") {

       writeln("int* var detected");
    } else {

       writeln("Unrecognised type");
    }
}
```
