That isn't going to help, as the clang linker devs don't look there.

That looks like linker output, and thus not a problem with the D toolchain. I guess that the linker you're using also has a suggestion feature. A quick Google tells me you're using a Mac?

I'm so used to D suggesting symbols that I didn't think this through, even though I remember seeing 'ld' in the output :-)

Yes, llvm/clang on a Mac.
