I have some doubts about the following code:
sub _Var ($$$;$) { # Wrkhorse code for manufctrd Vars
    #note $p->obj, $vn=varname, $wa=wantarray val
    my ($__, $p, $vn, $wa)=@$_;

  1. Why are you using prototypes in the subroutine definition? Unless you have a very very good reason to use prototypes, you should not use prototypes. And using prototypes to check the type and number of arguments is not a good reason.
  2. What do you think @$_ does? You are dereferencing the global default variable $_ into an array. Didn't you rather want to use the @_ variable which contains the parameters of the subroutine call?
  3. Are you using strict and warnings?

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
