> it wont even compile oh, sorry. Looks like I tested it using a modified compiler. I reverted patch [https://github.com/nim-lang/Nim/commit/e04f3195407cc99f958dd81e0a9d58fe5414e631](https://github.com/nim-lang/Nim/commit/e04f3195407cc99f958dd81e0a9d58fe5414e631) which apparently breaks some concept-related functionality. See [https://github.com/nim-lang/Nim/issues/4084](https://github.com/nim-lang/Nim/issues/4084)
@perturbation2 Can you please elaborate a bit more? I bootstrapped the devel branch of Nim compiler, applied your changes(as I understood them) and got the same error as @UnnoTed. This is the code: [https://github.com/akamaus/vindinium-nim-starter-kit/tree/buggy](https://github.com/akamaus/vindinium-nim-starter-kit/tree/buggy)
