Hi,
Good initiative!
Concerning Smallapack, please note that it did work on previous Pharo versions (at least up to Pharo 5).
It could still work on newer versions, but it requires the old compiler.
Indeed, Smallapack functions may have more than 15 arguments, so we must bypass a limitation of byte code.
The trick is to pass a single vector (Array) of arguments when they are more than 15.
It would be a good exercize to port the trick to the new compiler (Opal), and verify how easy it is to specialize this variant.
