GitLab

Output is fairly fabulous.  Really happy with this.

Diff size is nice.  Took the opportunity to do some cleanups and the
net result is 193 insertions and 351 deletions counted by line.

Most importantly, though: running 'go test .' in the gengo package
actually generates, compiles, and tests **everything**.

The test file inside the "_test" dir that you previously had to jankily
run manually is gone.  Hooray!

And already, we've got three distinct packages being generated and
tested.  (Try 'diff _test/stroct*/tStroct.go'.  It's neat.)

The time overhead is acceptable so far.  The total time is up to 0.9sec
on my current machine.  Not as bad as feared.

Overall: nice.  I think this reduces the test friction to a point that
will significantly enable further progress.
