Structs A and B do the same things, in different way.
Is there any difference/limitation between those?

The mixin variant generates a method. That means, you can
reference members of the struct in the function.
Silly example:
----
mixin template Test(T)
{
auto returnX() { return x; }
}
struct A
{
int x;
mixin Test!int;
}

With the alias variant you get an alias to a free function, not a
method. So you couldn't reference x like above.
What's nicer about the alias version is that you see what symbol
is being generated. It's obvious that `alias returnInit =
returnInitImpl!int;` creates a symbol "returnInit". In the mixin
variant, you have to read the template's source to see that.
