This comes from the fact that unless you are declaring a
template with `template`, you are using the eponymous template
trick under the hood.
Aaaah. It's so common, that one forgets about it. Thanks for
reminding. :-)
Note, putting unittests inside templates duplicates the unit
test for every
instantiation. Using an instantiation other than the template
itself is going
to result in a lot of duplicated tests. Unfortunately, there is
no mechanism to have a documented unittest that isn't part of
the instantiation.
I know about that problem. Would be good, to have some such
mechanism. Until we have, I'll resort to moving them after the
template and adding a link to the docs, see below.
This might be a bug. I don't know how this is built, so I'm not
sure. But it looks like the compiler isn't including some
instantiation of FormatSpec when linking.
I moved the unittest outside the template, just to find out, that
there is allready one, which is almost identical. I merged the
two and added a link to the docs, so people can find the example.
Thanks a lot!
