Thanks to dgp on #tcl on freenode for his suggestion for a stub for [interp alias] that let us run basic.test to completion!
We regressed on compile.test with the recent updates, but added five more spec test files that run to completion. That's 320 more passing tests, include a few extras in already completing files.
I also tracked down the expected boolean value but got "" error that is blocking many of the spec tests from running any tests; turns out that the constraint framework in tcltest.tcl (which helps determine if a given test in the file should be run or not) requires a minimal version of [trace] in order to work. Pulling at this thread, the trace refers to [namespace code], which means we also need [namespace inscope] ; I have a work in progress on each of these, but it's not quite ready for checkin. Thanks to pmichaud on #parrot for some thoughts on how trace (or tie in p5) might work on parrot.
