alias: variable is an object but is not an object

    The section on aliases starts by defining an object as a constant, a
    variable, a signal, or a file. Then, it continues with "NOTE 1— Since,
    for example, the alias of a variable is a variable". Ok, fine. This also
    means that alias of the (variable) object is (a variable) object. But,
    in the end, we read "NOTE—An alias of an explicitly declared object is
    not an explicitly declared object". Stop! Explicitly declared variable
    is not a variable anymore. How is this resolved?

    Hi,
    I think you got the wrong focus on the doubted sentence.
    It should probably be:
    An alias of an explicitly declared variable is not explicily declared anymore, since it has been aliased, still it will remain a variable.

    Hope I got it right that way.

    Have a nice synthesis
