Yes, but on the other hand it makes easier to switch from that interpreted 
language to C++ (for example). I'm quite sure that many people use Tcl to 
prototype their applications (or some part of it) and then switch to C++ 
because it was too slow or they were required to ship something in C++. For 
these reasons (and various others) I remember that I used to work with 
vtk*Collection in many parts of my Tcl developments.

They do. Or did I miss your point ? Collections are scattered in many 
places and returned by many methods (collections of actors, cameras, 
renderers, etc.). And it works in Tcl too of course.
