tar xzf archive.tar.gz ^D

It seems, that it does not work with tar.bz2 -files yet. And support for
tar.dct -files wold be nice, too.

It has for quite some time.  What version are you using?

Is there a version of tar that supports dact?

Not really. But it is possible to use dact with tar:

Pack:

tar --use-compress-program=dact -cvvvf roms.tar.dct roms

Extract:

dact -cd roms.tar.dct | tar xvvf -

You'll have to explain a little further why you think it doesn't work
with .bz2 files.  Completion of names from inside the archive is keyed
off the extraction arguments in the tar command, not off the file name,
so `tar Ixf foo.tar.bz2 <TAB>' will complete files from the .bz2, and
`tar zxf foo.tar.gz <TAB>' will complete files from the .gz.

You have to use the 1-letter short forms of the tar options; the _tar
function does not yet handle the long-word forms.

It depends which version of tar that you have ...

tar (GNU tar) 1.13.17
Copyright 2000 Free Software Foundation, Inc.
[...]
  -I, --bzip2                        filter the archive through bzip2
[...]

The tar completer interprets any of I, j, and y as options that mean to
use bzip2'd archives.

Just in case ... if writing new scripts, it's advisable to use 'j',
which various tar programs are settling on, migrating away from 'y'.

Hrm, OpenBSD tar(1) uses -I with a parameter for something else:
-----------------------------< cut here >-------------------------------
 -I file    This is a positional argument which reads the names of
            files to archive or extract from the given file,
            one per line.
-----------------------------< cut here >-------------------------------

Unfortunately, some quick googling hasn't turned up any evidence to back
up my assertion re '-j'.  :^(  Ah, hold on, FreeBSD 4 box, tar(1) manual
page, states:
-----------------------------< cut here >-------------------------------
COMPATIBILITY
     The -y is a FreeBSD localism.  The GNU tar maintainer has now choosen -j
     as the offical bzip2(1) compression option in GNU tar 1.13.18 and later.
     The -I option is for compatibility with Solaris's tar.

yeah i think freebsd is 'I' as well.  it's actually quite annoying -
i have to use all 3 different command line switches with different
machines that i run.
