I tried to change the code to this:
```d
void f(FUNC)(FUNC func)
{
     enum dg = () => func();
     T!int.f_new!dg;
}
```

But I get this error:
```
onlineapp.d(7): Error: delegate `onlineapp.f!(void function() 
@safe).f.__lambda2` is a nested function and cannot be accessed 
from `onlineapp.T!int.f_new!(delegate () @safe
{
(*func)();
return ;
}
).f_new`
```
