Just to add an opposing viewpoint: I first encountered Tcl when tinkering with Quartus, and initially hated it with a passion. Once I eventually figured out which types of brace to use in which context, and started to appreciate having variables and conditionals available in .sdc files, the loathing started to give way to a grudging respect. Now I really appreciate the elegant simplicity, the ridiculous ease with which it can be integrated into a C/C++ project, the ability to script JTAG communication with a running project (complete with Tk-based UI), the lack of dependence on any online repository or source of truth. But especially I appreciate the lack of churn, which means the same scripts will work with the current release of Quartus as well as a version from more than a decade ago (needed because newer versions dropped support for newer devices.)
