That's more of the anti-C++ fallacy. I think it won't help.

Arguably, it seems equally clear that anyone with a little background
in C++ finds the above declaration very clear, brief, and all on
one line, as should be.

The Ada example as given has incorrect syntax, because 16#A100#
alone is not of type System.Address.

Now Ada requires recent GNATs that support something which is
finally close to a single declaration, viz.

  use System.Storage_Elements;

  I : Integer with Address => To_Address (16#A100#);

(The old Ada syntax, "for I use at ..." is obsolescent,
but still present as well, and you start wondering why they
have changed this very fundamental expression three times.)

I think that typed literals would be even better...
