If it's a large tcl "app", then quite often that's the first mistake. I've seen large Tcl systems which work pretty well. A combination of different applications, cron jobs, scripts etc., with some C/C++ libraries for integration and performance-critical things. With the added benefit of having a pretty decent graphical toolkit on top. Won't be the winner of a GUI beauty pageant, but it works. And most of those systems were pretty old, so it's not like you had a lot of better options back in the days. Tcl was pretty awesome in the mid-90s. Most Java programs that replaced those enterprise tcl systems were a lot worse than their predecessors. For a new project? Maybe, maybe not.
