D doesn't have implicit constructors for function parameters 
otherwise you could do what you've described.

But you can currently construct a vector and assign it from an 
array, it just won't do it automatically for function arguments 
for the reason mentioned.

Example:
```
import core.stdcpp.vector;

// construct
vector!double v = [1.0, 2.1];

double[] a = [];
// assign
v = a;

void f(vector!double);
f(a); // error
```
