Hi, just a quick tip: ``` The actual term is: S2Eapp(S2Ecst(g0int_t0ype); S2Eextkind(atstype_int)) The needed term is: S2Eapp(S2Ecst(g1int_int_t0ype); S2Eextkind(atstype_int), S2EVar(6368)) ```
means, that you passing an argument of primitive type, but you need a higher kinded type (int n, where n >= 0 && x < 4) and (int y), where y >= 0 && y < 4 first try is to replace 'i' with g1ofg0(i). then compiler may ask you to prove, that i>=0 && i < 4 чт, 16 июл. 2020 г. в 12:12, d4v3y_5c0n3s <tmj9...@gmail.com>: > So, I'm trying to mutate a var twice in order to replicate some C code > that I am trying to port to ATS.
