Mission saved! > I'd like to design a language like this. If you add a quantity in inches to a quantity in centimetres you get a quantity in (say) metres. If you multiply them together you get an area, if you divide them you get a dimeionless scalar. If you divide a quantity in metres by a quantity in seconds you get a velocity, if you try to subtract them you get an error.
