So in 1995, I found out about a research project from Sun, a programming language named Self. Self was a Smalltalk dialect but *way* more dynamic--duck typing, but also duck inheritance and duck object layout. Despite this (and here was the research part) it was *insanely* fast.
Self was FOSS but only worked on SPARC hardware. Fortunately, I had access to the little (shared) Sun box the Computer Science Club ran.
This was, to be clear, beefier than any PC of the era.
