Here is TCL's author talking about its roots: http://www.tcl.tk/about/history.html
The Electronic Design Automation industry was in some ways ahead of
other industries in adopting TCL as its major scripting language but
because of this I think it might now be suffering because, as capable
as TCL is, current EDA tools would benefit from reflecting what is
increasingly an object oriented compiled language core, as Python
objects for user manipulation.
