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

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.
