I just figured it didn't work in general, but seems to be an issue with appending.

Oh, it is because of the implicit construction thing, see my answer here to learn more: http://stackoverflow.com/a/42285015/1457000

You can construct the named tuple from a tuple() but you can't convert one to another since the names change the type.

I don't think the language has a solution with this since you can't implicit construct nor overload operators on built in arrays (if it is a custom array, you can do an opOpAssign).

What you could do is

alias ShortName = Tuple!(int, "A");

ShortName[] a;
a ~= ShortName(3);

... of course, at that point, you can also just use a regular struct too...
