QOTW: "Tcl doesn't work ... it [plays]." -- Miguel Sofer

"The number one bug I see in other people's Tcl code is failure to
account for the possibility that a file name or pathname may have a
space in it.

Come on people! Pathnames can have spaces in them!

Even on Unix!" -- Stephen Huntley

I had lots of fun writing Tcl robot control programs when TclRobots
first appeared, and it's non-trivial do it right. So much fun, in
fact, that I wrote a Tk::TclRobots module for Perl/Tk that allowed you
to write your RCP in either Tcl or Perl, and they could battle each
other.

As you might guess, the language didn't determine the better RCP, luck
and good algorithms did.

No offense to crafty Perl guys out there, but two things I love about Tcl
are that the language lends itself to legible programs, and that the
community shies away from "gibberish as programming". Thank you, Tcl.
Thank you, Tcl'ers.

Perl allows the programmer to write legally open source, writing
effectively closed source.

The proverbial "write-only" language. I felt the same way about APL
when I was in college, although I loved the language and was fairly
fluent in it.

I am also reminded of the humorous rationale for not commenting your
code: "It was hard to write, so it should be hard to read, too".
