While not an exact solution, aliases can be a little useful here.

```d
import std.typecons : Flag;

// Shorten the names as much as you need of course.
alias Verbose = Flag!"verbose";
alias VeryVerbose = Flag"veryVerbose";

void func(Verbose verbose = Verbose.yes, VeryVerbose veryVerbose 
= VeryVerbose.no)
{
}
```

And you can of course do that for other types, e.g. `alias Opt = 
Options`

But again, this is more a workaround for why you're wanting the 
auto inference.
