I used Tcl by virtue of a software package in the scientific domain I work in called OOMMF which is old but a stalwart and very reliable. I find it an odd language. But the one thing that I think is very cool, is that it's very very simple to get a minimal Tcl interpreter (partcl) that can be embedded into a C/C++ application. It also still comes bundled in to Python for the Tkinter framework. You can even use it in Jupyter Notebooks now
