I loved go from 1.3 onwards, and it still has a special place in my heart. But ultimately a failed attempt at writing a heavy numeric/scientific app in Go soured me on the lack of generics. the overhead of needing to re-implement functions in order to avoid casts was way to much to bear in one app, and projects such as gonum suffer either due to an over-reliance on interface or the requirement to constantly re-implement functions to deal with the change in type signature between int, float, and their associated sizes.
