The link to alga crate has lead me to the ScratchPad II ( http://www.csd.uwo.ca/~watt/pub/reprints/1990-miola-spadtypes.pdf ), it's another example how in computer science lot of important ideas were invented lot of time ago. It seems to contain a perhaps better version of the Rust traits... :-/
agree. i propose, instead of "on steroids": "gone to Hollywood" . as in
