 set Variable "::Variable"

 proc TestProc {} {
     puts "::proc"
 }

 namespace eval Namespace {

     namespace eval Namespace {
         variable Variable "::Namespace::Namespace Variable"
         proc TestProc {} {
             puts "::Namespace::Namespace proc"

     variable Variable "::Namespace Variable"
