That would require a linker that's aware of D but as far as I
know, all system languages use the system linker.

Hmm, how about this:
During compilation, D generate undefined TypeInfo symbols, but it
also embed type information in the object file (like what Rust
does). And then, when dmd/ldc/gdc/whatever is called for linking
executables, it will scan object files and generate another
object file containing the TypeInfos, and link them together with
the system linker. If the compiler is called for linking shared
libraries, it doesn't.
