#265 Namespace collision

[Tim Tomkinson]

Starting in Itcl 4.0, two objects with the same name cannot be created in two different namespaces:

package require Itcl

itcl::class Class {}

namespace eval A {Class c}
namespace eval B {Class c}

This fails with the error:
INTERNAL ERROR cannot set variable "::itcl::internal::variables::c::Class::this"

This is due to the object's fully qualified name not being used in the "::itcl::internal::variables" namespace.

Will look at this along with the other variable troubles.

In the reported case, indeed, replacing simple names with
fully qualified names could resolve the matter. Generally though,
this is simply an unworkable scheme that must be replaced.

% itcl::class ::b::c {}
% itcl::class ::c {}
% c ::a::b
::a::b
% b::c ::a
INTERNAL ERROR cannot set variable "::itcl::internal::variables::a::b::c::this"
