Actually, that might be good for a side-by-side comparison.
The Ruby version is way cleaner.

How about solving that puts() gripe you mentioned:
sub twice (&) { my $sub = shift; &$sub; &$sub; }
sub puts { print "$_\n" for @_ }
twice { puts "Ruby rocks!" } # Now in Ruby *AND* Perl!
Ugly, but flexible. No point condemning a language just because
it doesn’t use an entirely different function to tack a newline
onto arguments. Much better to discriminate based on appearances.

How about solving that puts() gripe you mentioned:

also, I use a shell function rather than an alias, this way I
can make it works when there is no parameters (reading from
stdin) :
vmore()
{
if [ $# -eq 0 ]
then
vim -u ~/.vim/rc.more - -c ‘:set nomodified’
else
vim -u ~/.vim/rc.more “$@”
fi
}

I’ve seen this information before, but can’t find it at the moment:
How do you get the ^V into Vim on Windows … where ^V means “paste”

That reminds me of something. Create a $HOME/.vimrc.more
containing this:
[ snippage ]
and alias “vmore” to “vim -u $HOME/.vimrc.more” and you have a
pager that does RUBY syntax highlighting.
In $VIMRUNTIME/macros there are two files: less.sh and less.vim.
less.sh is a drop-in replacement for less and takes care of just
about everything for you. You may want to store a local copy in
your ~/.vim/macros/ with tweaked settings, but it’s in the
standard distribution for a while now.

The point was that for this particular challenge being able to iterate
with both the element and the index and having puts are advantages.

I took the information from vim.org. It did work so I didn’t try to
look for improvements.

Not all shells have functions…
Anyway: I don’t know of any other pager that has syntax highlighting
- syntax highlighting for Ruby in particular.
