all right,Richard.i pretty agree with you and always think that NOT 'many'
but ALL languages should have Variety Scope.

And i do not want access the ALL variety in any function/page,as you said,
that's poor design.

I just feel a bit surprise that the function can not access the variety
which located and defined in the same/current page except the GLOBAL
modifier.(although the thinking  is wrong in fact later)

That's all.
