I was experimenting with -betterC and found out that C++ classes

Nope.
Could we remove T.classinfo and make classes work under -betterC? Or
is there some other reason preventing this from happening?
Thanks.
Definitely not.
Classes require vtable's to work. Vtables are generated as part of
TypeInfo. No TypeInfo, no classes, simple to understand.
No. vtables can be generated without RTTI and we can have both D and C++
classes in betterC mode. It may not be ready now, but it is definitely
possible and should be supported.

Agreed, but that is a bigger change and would require a bit more of a
rethink than just a simple 'remove reference to symbol'.
