I tried to write a GCC plugin to do it once, but there was no plugin
pass that sees the code as it's parsed, plugins can only interact with
the optimizations passes doing codegen. That means it would only see
the names in templates and inline functions if they're instantiated /
odr-used.

That was quite a few years ago, so it's possible there are more passes
made visible to plugins now, so maybe it would work.
