I can't believe I missed that, so I looked carefully at what I did.
Relative to your example, the minimal difference is this:

    function a() print(debug.getinfo(2, "n").name) end
    function b() return a() end
    b()
nil

It is instructive to work out the reason why in this case there
is no name.

Thanks!
