Is there a Bash way to pipe stdout and stderr *separately* through ddemangle?

I'm aware of

    2>&1

but this removes separation of stdout and stderr.

2>&1 means "redirect file handle 2 to the same as file handle 1".
So it will redirect stderr to stdout. I'm not exactly sure what you want
to do though, so this might not be the answer you are looking for.

You can use process substitution [1]:

dmd ... 2> >( ddemangle >&2 )

(or leave out the >&2 if you want the output of ddemangle to stay on stdout)
