Not so much now with the likes of Arduino, Raspberry Pi, ESP32 which have rich tool sets, but in days of old when you would get a piece of new silicon it was common to roll your own macro assembler in LISP.

This during a time when you paid for your dev tools. I remember being quoted the C compiler and SDK for a silicon graphics workstation in 1992 for U$5000. The rep told me it would only be U$3000 if you bought it along side two or more workstations on the same order.

Also. Cool AF article. Was neat to read and see lots of irritating, silly parentheses again
