I am very glad to see you here. It is valueable every time, if we
can draw attention of these who have used Ruby for a certain time.

As I hope that Ruby can become more international in future, I enjoy
everybody comes from ruby-list to ruby-talk :-))))

Ey... as long as you can make clear your opinions, there is no poor
English, IMHO. :-) Furthermore the more you use it, the better you
become, neh?

And me, for example, like that! The most exellent languages have no
debugger build-in (Ruby, Python, Perl ;-) Only interfaces are
forseen. So if somebody doesn't like a certain debuuger, simply write
a new one, without dragging the old one as uneccessary ballast!

Powerful, yes! But it lacks comfort. Except the ruby-debug.el, of
course. But due to we only have debugging hooks perhaps the future
will show us a debugger with a GUI like in Python or Perl.

Do you know TeX? TeX is a typesetting system; a language you use to
structure text during write. No WYSIWYG! After compilation the text
can be print out. Very beautiful.

I have scanned my hand-written signature, used MetaFont (part of TeX)
to generate a TeX font out from the scanned-in GIF file, and then use
the self-defined command `\cle' to insert my signature on that place
in my text ;-))) In TeX, nearly all commands begin with '\'.
