yes, sir Matz. I've already also tried that and I like class vars. But how
can I answer my peer's question, "duh, and your telling us to change our
sh/perl scripts to that? I thought you said ruby is easy to our eyes and
brain, botp?" ?

my humble request is: can we not extend "locals" to embrace scope outside so
they may act like class vars?

something like this i want if possible,

# script.rb
#---------------------
classvar x   # maybe, we may declare x as a class local var (just my term)
             # as if x now has nature like @@x

x=1
def mx1
   p x    #-> 1
end
p x       #-> 1

def mx2
   x = 2  # same x updated
   p x    #-> 2
end
p x       #-> 2

It is really @@x but without the @@.
I hope i am not asking too much :(

Again, thank you for answering newbie questions like this.

kind regards -botp
