Would a Tcl-aware Eclipse matter? Maybe yes, maybe no; in any case,
there's more than one way for Tcl and Eclipse to get along, and there's
more than one way to have an IDE and/or syntax-(partially-)aware
editing for Tcl source.

Thanks to Arjen Markus for his report from the Wiki(s):
The Wiki is a great place for watching some of the trends in the
Tcl community - this week we have a lot of attention for the "functional
programming" style :)
Functional programming:
- Composing functions revisited: Richard Suchenwirth minimises the
way to do that in Tcl - <http://wiki.tcl.tk/2755>
- You remember your first steps in multiplication? 1 x 1 = 1, ...
Too simple? No, watch the master of minimalism at
<http://wiki.tcl.tk/13919>
- To Apply a function to each item in a list and thereby to
get a new one - tis a consommation functionally to be wished
- <http://wiki.tcl.tk/13920>
- Beyond the confines of functional programming lies the world
where a program writes a program ... and that is
called genetic programming - <http://wiki.tcl.tk/13928>
Just plain old problems and their solutions:
- Encodings cause a problem at the C level ... or on the Tcl
level - anyway: <http://wiki.tcl.tk/13917> if you want to
solve this puzzle.
- Pastel colours can be picked via the HLS model for defining
colours ... <http://wiki.tcl.tk/10330>
- Do you have problems with floating-point numbers that are too
big or too small, but you do not care about precision beyond
the 12 digits offered by Tcl? <http://wiki.tcl.tk/12923>
is the answer!
Carpe diem:
- Let us never ever forget: To Have Fun With Tcl -
<http://wiki.tcl.tk/13723>
- A good tutorial makes an immense difference to beginners.
Tcl's are slowly improving.
