Examples of Tcl *.test files using the recommended technique: chanio,
cmdMZ, encoding, error, fileSystem, iogt, io, main, parse, source.

This is more important in the Tcl test suite, where the default mode
is -singleproc 0.  The namespace separation helps avoid bad surprises
on occasional tests of the -singleproc 1 mode.

The Tk test suite defaults to -singleproc 1 (no one wants to pay Tk process
startup costs for every *.test file) so any troublesome conflicts are
going to get detected quickly.  In that circumstance, namespace protection
is less important.

Use this:

	package require tcltest 2.2
	namespace import ::tcltest::*

I'm assuming your work is aimed at the test suite to go with Tk 8.5.*
and later.  This implies a Tcl version of at least 8.5.0 as well.
Version 2.2 of tcltest has been available since Tcl release 8.4.0.
The misfeature of [namespace import] that lead to all the -force-ing
has been fixed since Tcl 8.4.12.  Code for the future, not the past.
