What about line numbers? I think we only have them on Win64.

DWARF uses a weird state machine for efficient representation of file/line
information. Doable but not trivial.

It's GPL just like binutils. IANAL, but I'm not sure about dynamically loading
GPL libs. I know the GPL forbids redistribution of any programs that include
the library... Doesn't that mean that it would make it impossible for e.g.
Linux distributions to distribute non-GPL D software together with the library?

This seems to only support binutils and elfutils, both of which are GPL.
