No, I tried both combinations and neither works.

```
stealth_prefix prefix{0, 0};
error C2661: 'libbitcoin::stealth_prefix::stealth_prefix' : no overloaded function takes 2 arguments
```
```
stealth_prefix prefix = {0, 0};
error C2661: 'libbitcoin::stealth_prefix::stealth_prefix' : no overloaded function takes 2 arguments
```
Note that the same construction **does** work in libbitcoin but it's within the scope of a function:
```
stealth_prefix prefix{2, 0x691cf48b};
```
