Just saw another linker error in d.learn, and it got me thinking
dmd just calls the linker, and the linker spits out link errors. But
what if we had a 'linker wrapper' program which translated mangled names
into demangled names? It would at least help people understand the
problem better. How many times does a newbie come back and say "I have
this problem, and dmd spits out some weird message I don't understand"
and it takes a person who half-speaks mangled d names to understand what
the name is.
Given that D already includes a demangler, wouldn't it be rather trivial
to write this program in D?
I know it would make my life a bit better.
Thoughts? Takers?

I suggested that previously [1], and I think that need to be a part of DMD
for a simple reason: some of the names can't be demangled because their
are somewhat "hashed" to avoid limitations such as long literal name. E.g.
"_D4math6Mбrix9х44F32__T3addTCЂ–ЎZЂ„ќFЂ—ќЂґЂ—".
Given that dmd calls a linker internally, it could also retrieve linker
errors (if any present), translate and then show them, with a list of
suggestions to fix the problem if possible. Here are an example:
module test1;
void foo() {}
module test2;
import test1;
void main() { foo(); }
#dmd test2.d
Desired output: Error: No implementation found for method void foo()
defined in module test1. Try linking with test1.d
Actual output: Error 42: Symbol Undefined _D5test13fooFZv
