    Tcl namespaces follow a hierarchy, and in terms of syntax, use
    '::' to seperate namespaces.  Each namespace can have variables
    that are local to it.

<pre>
namespace <span class="keyword">eval</span> foo {
    set foovar 1
    namespace <span class="keyword">eval</span> bar {
	set barvar 1
    }
}

puts $::foo::bar::barvar
puts $::foo::foovar
</pre>
