This doesn't work (crashes) on windows. It probably does on Unix.
The XTRN flag is wrong there. On WIndows, it tells the en/decoder that
the template pointer is actually a pointer to a "chooser" function,
but the chooser function got moved up to the PointerTo template.
So, I moved the XTRN flag up to the PointerTo template, and that
didn't crash, but it failed. I'm debugging it now.
