QOTW: "We have memory leaks in our C++ based extensions, and the Solaris
and Linux memory management methods can vary wildly... but Tcl is as
stable and reliable as the U.S. economy... er, how about a '63 chevy with
a 283 V8? Yeah, as stable and reliable as a '63 chevy with a 283 V8."
"I think the need for OO techniques is greatly reduced by a language with
[eval] and [info] and dynamically-sized structures built in. This may be
why you see less OO in Tcl than in some of the other languages."
-- Darren New,
"What I like about 'bgexec' is that it handles all the dumb stuff under
the hood--so you (the Tcl programmer) don't have to worry about it."

The first 8.4 beta of the Tcl/Tk 8.4 Core has been
released at SourceForge.
ActiveTcl binary releases for Windows, Linux, and Solaris:

Michael A. Cleverly announces nstcl 1.0, "a Tcl package
which reimplements many of the useful APIs and commands

Techniques for building standalone deliverables are discussed
in the thread "Compiling or wrapping?". Techniques covered:
ProWrap, FreeWrap, Mktclapp, TclKit, scripted documents
(recently rechristened "StarKits"), and StarPacks:
More on Starkits and Starpacks: "Due to the many terrific
contributions and enhancements (most of them in the Tcl core
by now) you can now consider deployment of applications built
upon Tcl/Tk to be 'solved'. [...] Starkits are very close to
becoming a 100% hassle-free deployment technology."
