ompression method number.
Notice also the distinction - zip an archive format (put lots of files in
one file and take them out again) which allows entries to be compressed.
tar is just an archive format, gzip just a compression system.

abhor is the idea of hardwiring the zip assumption deeply into
our design.
I would agree - hardwiring is to be avoided.

5: not sure if it's a sick hack or an elegant hack
It is also possible to place the include zipfile on the end of the perl
executable and put $^X in @INC to make a 1 file perl distribution, but
I don't think anyone ever tried this

Do we really want to use tar format (over say cpio) as tar rounds files
up to 512 block boundaries, and has some arbitrary restrictions on filename
lengths in the headers?

certainly possibly to read raw memory with suitable (ab)use
of pack and unpack in perl (P and p)
I can't remember if it's possible to write to raw memory, and I'm
not currently on an operating system where I can test this sensibly.
But it's not obvious, safe or portable.

Yes. I think I suggest something similar (doing it per array) but Bart's
explanation made me realise this was not wanted. One doesn't want to change
the array in any way, just how the local code sees arrays. Its use can
still be discouraged, but that's not the same as saying "never use this"
