You're wrong, reread what Aaron said. The CURRENT dpkg is what the entire
distribution relies on. The CURRENT dpkg is written in C. You should be
If you believe it would be better to rewrite dpkg in C, go for it. More

Interesting. So you prefer bloated program code instead of bloated binaries?
The time a human needs to understand and maintain a program is less
valuaable to you than a few kilobytes of source code? People read program
code, but they almost never read binaries directly.

Some compiler bloat. The language does not.
And bloat is put a bit too simple. I don't care about a few kilobytes if it
has direct and noticeable positive effect in the source code.

You would be surprised what problems people have with all this pointer
You would be surprised what problems people have with all these regular
You would be surprised what problems people have with all these parentheses.
You would be surprised what problems people have with all these gotos.
You would be surprised what problems people have with all these mnemonics.

How scary. What exactly is the problem with a bigger binary?

See, I am the maintainer of libgtkmm. This is a huge wrapper library around
Gtk, which uses a lot of templates, classes, derivation, whatever. The
maintainer (currently about three people are actively working on the code)
were able to maintain compatibility even with g++ 220.127.116.11 (which is
horribly broken in every respect) until recently. I don't see them rewriting
their code everytime with another egcs release.
