TCL is such a neat language. I haven’t written that many blog post about it but it’s about as expressive as Perl. A true GTD language.
I remember that when I started learning Python about 20 years ago I used to write a Python script with a quick and dirty tkinter interface on my Linux desktop at home, I was then copying everything on a floppy-disk in order to use that script/program at work, on a Windows machine (with the help of py2exe, another very nice tool).
Thank you
