I thought it was a first step for runtime reflection.
The thing about runtime reflection is you only need it for a few
classes, while the compiler is doomed to generate the info for all of
them. Andrei suggested a better design, which was to use compile time
reflection to generate runtime information, as a library routine, on an
as-needed basis.
If we can't relay on runtime reflection being there it's basically
useless. It's like your idea that the GC shouldn't be optional. Then all
library code needs to be written to work without the GC. It's the same
thing with runtime reflection.
This is a lib issue. phobos should provide a standard way to do
compiletime -> runtime reflection so each lib doesn't need to provide
its own way every time.
I think you're misunderstanding.
The point is that without built-in runtime reflection, reflection is
only available for select classes that the programmer specifically asks
to have RTTI for. This is useless. It doesn't enable discovery-based
reflection at all, which is what makes runtime reflection in C#, Java,
... so useful.
