:   '''[namespace] path''' ?''namespaceList''?
Returns the path of the current namespace, or sets it to the list of namespaces ''namespaceList'' if that argument is given.
The path of a namespace is used to “resolve” command names that do not start with a namespace qualifier (''i.e.'', are not fully qualified) when those commands are not present in the current namespace.

[wdb] This command shows or extends the namespace
where an input command is searched in.

In this example, the namespace is extended:
======
% namespace path "tcl::mathfunc tcl::mathop"
% 
======

Now, you can input math-related commands as follows:
======
% hypot 3 [+ 2 2]
5.0
% 
======


In this example, the namespace extension is shown.
======
% namespace path
::tcl::mathfunc ::tcl::mathop
% 
======

Note that the namespaces argument is ''one proper list''.
It is not possible to input namespaces as single arguments.
(Is it a matter of discussion if that should be possible?)

Note that each namespace (including the global namespace) has a different path. For example:

======
% namespace eval test {namespace path ::tcl::mathop}
%
======
inside newly created namespace test, path is extended to ::tcl::mathop. Now, check it out:
======
% namespace eval test {namespace path}
::tcl::mathop
%
======
Indeed, path is extended. Now check it in namespace ::
======
% namespace path
%
======
In namespace ::, obviously there is no path extension.
Check if ::tcl::mathop::+ is known in namespace test:
======
% namespace eval test {+ 5 6}
11
%
======
Check the samein namespace :: leads to failure:
======
% + 5 6
invalid command name "+"
% 
======
