i have a piece of code which i managed to reduce to [this minimal
form](https://play.nim-lang.org/?gist=c4bfec49071f6afa42e266437781eeec)
import sequtils
type
Color1 = array[1, int]
Color2 = array[1, int]
Color = Color1 | Color2
Image1 = seq[seq[Color1]]
Image2 = seq[seq[Color2]]
Image = Image1 | Image2
template b(c: Color) = discard
proc appl(img: Image, k: seq[seq[int]]) =
echo k.foldl(a + b.foldl(a + b), 0)
appl @[@[[1]]], @[@[0]]
which fails to compile with
.nim(16, 1) template/generic instantiation from here
in.nim(14, 20) Error: 'b' has unspecified generic parameters
im probably doing something wrong with template, but if i would change the
signature of the `appl` proc from `Image` to `Image1` or any other type it
works normally. and why the `b` from `foldl` gets confused with template. sorry
if im being a brainlet and missing something obvious.
