TA> Don't use nested mustaches.
This should probably be a FAQ. :^) FWIW, what helped me understand this is
that the mustaches aren't saying "here's a variable" (in which case you
might think, incorrectly, that you need to put them around all variables
all the time everywhere), but rather "start parsing this as Jinja", and
that once you say that, it keeps happening until you close the mustaches
(which means "stop parsing this as Jinja"). One of the things that happens
when you're parsing as Jinja is that variables get expanded, but thinking
of it as "start Jinja" and "stop Jinja" helped me keep it straight when I
first started with this stuff, anyway.
