'''namespace current'''

Returns the fully-qualified name for the current namespace. The actual name of the global namespace is "" (i.e., an empty string), but this command returns '''::''' for the global namespace as a convenience to programmers.

----
Wondering: how is namespace current ''convenient'' to programmers ? Consider you want to return a fully qualified variable, no matter in which namespace you are.

 return "[namespace current]::variable"

doesn't work for the global namespace;

 return "[namespace current]variable"

only works for the global namespace. If the variable doesn't exist yet, [namespace which] won't help either. So someone mind explaining to me why exactly this is ''not'' '''inconvenient''' to programmers ? Seems I got tomatoes on my eyes.

 namespace eval bla { variable v }
 # now how do I give a FQN of v (::bla::v here) as -textvariable ?
 # here [namespace which -variable v] would work.
 # but ...
 namespace eval bla { widget .bla -variable [namespace what-exactly var] }
