BTW, this looks like a particularly bad piece of engineering.
The trouble is, it saves an index to the member, then does a
bunch of semantic processing, then deletes what is on that
index. But what if the members[] in the meantime shifts around?
There is an assert for that case, so it at least won't cause
corruption, but it looks bad.
IIRC I was involved in this somehow. It has been some time, but I
think the deal is that it only does so when all the other members
that might have been added in the meantime have also been
removed. I suppose it seemed like a good idea to save that local
information locally instead of increasing the size of
TemplateInstance by a pointer, of which there might be a
bajillion instances in a typical "modern" D program.
