The following code example illustrates how different types of
namespace path addressing effects what is being accessed (Variables) or executed (Procedures).

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"
proc TestProc {} {
puts "::Namespace proc"
}
proc test0 {} {
puts "$::Variable"
}
proc test1 {} {
puts "$::Namespace::Variable"
}
proc test2 {} {

}
proc test3 {} {
::TestProc
}
proc test4 {} {

}
proc test5 {} {
