I suggest you read up on »Tcl stubs«, which is a feature that was introduced in Tcl 8.1 especially to make Tcl extensions in C usable with different (notably future) versions of Tcl. I used to do a lot of C-level programming with Tcl and this proved to be a very valuable feature because you didn't have to recompile your extensions whenever a new Tcl version came out. So no, you don't need to »recompile the world«, and indeed that is not something the Tcl authors recommend – they recommend using stubs instead so your extensions will be compatible with future Tcl versions without recompilation. In other words, you're wrong.

Yes, Tcl stubs is about what's needed for the stable ABI. So we have at least one scripting language whose authors are serious about compatibility. Now we need to convince developers of extensions to use this mechanism, but this is indeed a good start. Too bad the Tcl itself is not all that popular. And there is also the unfortunate fact that distributions often don't use Tcl stubs but link with one single version of Tcl directly - but yes, in this particular case authors of the language did their part.

As it is, Tcl/Tk remains one of the better-kept secrets of the industry; lots of people use it as a work horse but it isn't as »hip« as some of the other languages in the same space – even though it is very well engineered and documented and has been quite innovative in lots of areas. For example, Tcl offered full Unicode support with the release of Tcl 8.1 in 1997, way before any of the other popular languages followed suit, and of course Tk revolutionised X11 GUIs in the early 1990s when everyone else's idea of GUI programming involved C and OSF/Motif. Tcl/Tk can do things like cross-platform single-file deployment that are very helpful and simply not available with most other similar languages. Too bad it doesn't get the attention it deserves.
