I learned #scheme back in 1994 or so, at Iowa State University, where the CS dept was very progressive and theory rich. Used it a bit after, and I remember when #guile got adopted as a GNU scripting language around 1998 or something. Now 25+ years later #GUIX is pretty sweet, and I see guile has a byte code compiler and templating JIT. So guile is dramatically more capable than something like bash. The future is now!
