Research direction
The issue proposes a Reverse type class and two instances using Symbol.Cons and Symbol.Append, but names no files or tests. First read the repository’s existing type-level Symbol definitions and tests to find where a similar operation belongs. Done means the proposed reversal works for empty and non-empty Symbols and has coverage in the project’s tests.
Written by the indexing model from the issue text.
Description
class Reverse (s :: Symbol) (r :: Symbol) | s -> r, r -> s
instance reverseNil :: Reverse "" ""
else instance reverseCons :: (Symbol.Cons h t s, Reverse t u, Symbol.Append u h r) => Reverse s r
