I was experimenting with -betterC and found out that C++ classes doesn't
work. Because the resulting object file needs a symbol

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.
Same reason why you can't use classes and cross the dll boundary on Windows.
But if you prefer not having any methods to call, then I'm sure we can
remove the requirement on the vtable ;) (Not a solution)
