Re: [boost] [boost-ext] Looking for Review Manager/s

      Great question. There are multiple ways of distinguishing them but IMHO
strong types would be the most elegant/encouraged when used with DI.

struct X {
  name_t name;
};

struct Y {
  title_t title
};

auto injector = di::make_injector(
  bind.to("name"),
  bind.to("title")
);

Alternatively, named annotations can be used too
- https://boost-ext.github.io/di/tutorial.html (search named or annotations)

Or what it's called a context injection

auto injector = di::make_injector(
  bindstd::string.when<X>.to("name"),
  bindstd::string.when<Y>.to("title")
);

This brings up one pretty obvious question, what if I have two constructor
parameters of the same type:
struct X
{
    std::string name;
};
struct Y
{
    std::string title;
};
struct Z
{
    X x;
    Y y;
};
How do I inject specific values for X::name and Y::title?
