Why should there be any difference between:

    int J;

and

    typedef bit signed [31:0] myint;
    myint J;

Imagine a module with a parameter type:

    module m #(parameter type t = int) ...

Within the module you might want to query $left(t), etc.
Do you really want the module to behave differently depending on
whether int or myint is passed as the type parameter?
