Well, this program ceased to work:
--8<------------------------------------------
set mytest 1
puts $mytest
namespace eval myspace {
global mytest
puts "mytest in myspace is $mytest"
}
-->8------------------------------------------
So, what is global doing then?
Here, http://wiki.tcl.tk/1508, I read that global foo is
equivalent to upvar #0 foo foo.
That is not quite the case anymore, because, when I replace "global
mytest" by "upvar #0 mytest mytest", the above program works again.

The error I get is:
$ tclsh8.5 foo.tcl
1
can't read "mytest": no such variable
while executing
"puts "mytest in myspace is $mytest""
(in namespace eval "::myspace" script line 5)
invoked from within
"namespace eval myspace {
global mytest
#upvar #0 mytest mytest
puts "mytest in myspace is $mytest"
}"
(file "foo.tcl" line 5)
