I used to work at a place whose webserver was in TCL (AOLServer). Once I figured out some of the gotchas, I learned to really like TCL.

Like you mention, it's used as glue in lots of places, for instance in my Electrical Engineering classes to glue together VHDL/Verilog and program FGPAs.

I have a friend who worked as a principal developer on an EDA product from Synopsys. It was amusing how he converted all of the product and product acquisitions into TCL and whatever compiled language + a c lib so he could invoke the feature from TCL.
