QOTW:  "I understand that is the substitution nature of Tcl, however I
can see that being a common mistake with the new behavior that might be
missed." - USCode on {incr $i} in 8.5
    

    Alex shows how easy it is to keep a healthy distance from
    the C-Tcl API:

Thanks to Arjen Markus for his weekly summary of Wiki action:
  The Wiki seems to be gaining yet another feature - a summary
  of the changes. We'll see how useful that turns out to be.
  Meanwhile: here is the weekly summary.
  
  Development tools
  - Need a GUI-builder? Maybe TkVSform is something for you.
    This has been revived recently: <http://wiki.tcl.tk/2477>
  
  - Itcl-ng is based on the TclOO extension, check out the
    latest news at: <http://wiki.tcl.tk/19873>
  
  - Dou you know Swig? If not and you are extending Tcl with
    a C library, definitely have a look: <http://wiki.tcl.tk/719>.
    Or perhaps, for some examples, go directly to this French page:
    <http://wfr.tcl.tk/1693>
  
  Fun stuff
  - Get the code from these pages and manipulate it a bit, 
    that is what Twig is all about. Examples and questions answered
    at <http://wiki.tcl.tk/21913>
  
  - Stick figures, anyone? Or better: is it possible to do  
    animations like the ones referred to on this page -
    <http://wiki.tcl.tk/21905>
  
  Serious stuff
  - As we all know floating-point arithmetic is a black art. 
    Or is it simpler than that? Well, it turns out to be 
    fairly simple to obtain its characters with Tcl in the same 
    way as a library like LAPACK does: <http://wiki.tcl.tk/21926>
  

Everything Tcl-related you want is probably one or two clicks away in these
pages:
    The "Welcome to comp.lang.tcl" message by Andreas Kupries
        http://www.purl.org/net/tcl-welcome
    comp.lang.tcl is a crucial resource for Tcl practitioners.
    An interesting perspective on its traffic appears at
        http://groups.google.com/group/comp.lang.tcl/about

    The Tcl Developer Site is Tcl's "home base".
	http://www.tcl.tk

    Larry Virden maintains a comp.lang.tcl FAQ launcher.
        http://www.purl.org/NET/Tcl-FAQ/

    The Tcl Developer Xchange is a highly organized resource center
    of documents and software with provisions for individuals to
    maintain references to their own software:
        http://www.tcl.tk/resource/
    The TDX sponsor, ActiveState, also keeps info to convince your
    boss Tcl is a good thing
        http://www.tcl.tk/scripting/

    The Tcl'ers Wiki is a huge, dynamic, collaboratively edited repository
    of documentation, examples, tutorials and pontifications on all things 
    Tcl.
        http://wiki.tcl.tk/0
    For the ideal overview of the topics about Tcl most likely to
    interest a newcomer, see "Arts and Crafts ..."
        http://wiki.tcl.tk/969
    There's also a high-quality Wikibook on Tcl:
        http://en.wikibooks.org/wiki/Programming:Tcl

    ActiveState maintains binaries distribution and development tools
        http://www.activestate.com/Tcl
    along with a Cookbook of Tcl recipes
        http://aspn.activestate.com/ASPN/Cookbook/Tcl

    "La Gazette du Técleux" is an important monthly publication.
	http://wfr.tcl.tk/1159

    deli.cio.us presents an intriguing approach to reference commentary.
    It already aggregates quite a bit of Tcl intelligence.
        http://del.icio.us/tag/tcl

    Cameron Laird tracks several Tcl/Tk references of interest (but
    needs to validate many of the links).
        http://phaseit.net/claird/comp.lang.tcl/

    Years ago, Cetus Links maintained a Tcl/Tk page with verified links
        http://www.cetus-links.org/oo_tcl_tk.html

    "Yahoo! Groups" archives comp.lang.tcl.announce posts--even 
    though clta itself is dormant.
        http://groups.yahoo.com/group/tcl_announce/

We're working on more useful archives of past installments.  Dave 
Williams generously is building up
    http://www.bacomatic.org/~dw/comp/tclurl/index.htm
and of course Google gives us
  http://groups.google.com/groups?oi=djq&as_q=+Tcl-URL&as_ugroup=comp.lang.tcl

Suggestions/corrections for next week's posting are always welcome.
