Refactoring Case Change Code to Idiomatic Emacs Lisp
I asked Xah Lee for feedback on my case changing functions. He’s fluent in Emacs Lisp, so I figured if he wanted to, he would’ve used my approach years ago. So there must be something I miss. The factoring of the small helper functions don’t seem to be bad, but there are other reasons to design the text editor you use every day in one way or another:

Maybe nobody is suprised that the book “Structure and Interpretation of Classic Mechanics” by Sussman & Wisdom contains code that you can put in any old Scheme/Lisp environment to actually represent mechanical equations.
