i think this looks nice but realistically only cleans up v simple cases. a lot of the very-verbose-and-not-so-elegant-looking multidimensional math stuff looks "worse" than other languages because go doesn't have operator overloading. it is not clear to me this improves syntax too much in practice on it's own. (this is not a request to add operator overloading but merely the non-controversial statement that operator overloading can help math-heavy code look more "hand drawn" sometimes).
the gorgonia example is indicative of the issue: nil may be less aesthetically pleasing than ":" (or not) but it's unlikely the surrounding code looks anything like the math as expressed on paper by hand either. gonum is quite convenient even with this...code that uses it can look a bit more 1960s than other languages but it is simple and super-clear. i like that i am never (read: rarely) confused by () or , or [] etc characters in go. if you could find a way to cover more ground the change would look more compelling to me.
