Perl golf article at Perl Monks

A new article on Perl Golf has appeared at PM:

Someone has enquired about the true identity of Ton Hospel
and I didn't really know how to answer.

Nice. Perhaps it'll prompt a new compo soon :)

Ahhh .. how I long for the good old days.
Speaking of that, there was a post yesterday on
comp.lang.perl.misc asking about a one-liner to
reverse the lines in a file in-place. So the input
file itself must be modified and no other files must
be created.

I came up with this:
perl -aF"\n" -lp0 -i -e '$_=join$\,reverse@F' in.file

But then, I remembered Eugene's (in)famous solution to
reverse sort, but couldn't get it to work:

perl -pi -e '$x=$_.$x}{$_=$x' in.file

This prints to screen, not back to the file.
Any takers?

Traditional way:

perl -i -ne 'unshift@_,$_;eof&&print@_' in.file

So do I, so do I. In fact, as nostalgia settles in, I've found
myself toying more and more these days with a type of competition that
would both encompass the Hermetic arts of golfing and allow for vicious
interaction between players. What I came up with is a Perl variation on
the old venerable Corewar game that, I think, might be great fun. For
some demented definition of fun, it goes without saying.

In all cases, I have attached to this post a draft of the rules of
the game. I hope to have the game engine (plus a web / email interface)
ready by mid-April. So if anyone's curiosity is piqued by the thing, I
might try to organize a public tournament then...

Joy,
`/anick
PS: Wonderful article, /-\ !

Yes, we all have to play this game! But have you considered a variant in
which the maximum snippet length decreases as the game goes on? This would
make the game progressively harder as you get towards the end.
