Except it's not entirely explicit. It allows the type name of the object being constructed to be elided.

Per the article, this is the explicit form:

    var gpa = std.heap.GeneralPurposeAllocator(std.heap.GeneralPurposeAllocatorConfig{}){};

I don’t think type elision make the codes execution less explicit. Nothing else could go there

That's a textbook definition of "implicit", as in not directly specified, but assumed.

The fact that unacceptable parameter would fail compile time validation does not make it any more readable.

Consider this:

    var foo = OpaqueTypeName(.{}){};

What is the . eliding?

You don't know. I don't know. It's impossible to tell because the type is opaque to our understanding.
