My exposure to TCL, or rather dialects were through Autodesk Maya (The MEL Script there seems a bit like TCL, IMHO). The other thing was Metal Gear Solid (PSX). Konami used TCL to set up the level entities - enemies, traps, etc. Internally each command was hooked through a "C" function that took argc, argv, and to my shock (and then grin), there were tons of "C" functions that we working like main() - e.g. parsing arguments. For a moment I thought - this must be slow, then I understood - it did not matter - it served it's job, and allow non "C" programmers (game designers, scripts) to set-up objects easy in the "C" world. The whole thing had to fit in 2MB along with textures. Later working at our studio, I've stumbled on couple of sound tools written in TCL, and lately had to dabble once in a while in the MacPorts land (also TCL). But then most of the people I've asked they don't know about it...
