-Long term goal: Run the tcl test suite. Will an older one, be easier to
pass?
-Yes, much easier. We still have a ways to go, however. To run all the tests,
-run tclsh, sourcing "<tcl distro>tests/all".
-
-The sooner we can do this, the better, as I only want to have tests for
-internals, not for any Tcl.
