There is also an updated version out (with my name on the cover, to boot:-)

Although even that is not super recent.

Tcl's C API is very pleasant to work with, and its C code is a good read - except for the regex stuff, which are the first few files you'd see in an alphabetical listing.

I actually like Tcl quite a bit even if I don't use it much these days: (See the cover for all of the authors' names :-)
