zero-functional / zero-functional

I got this on Nim 0.20 on mac os x, just after import zero_functional

Nim Compiler Version 0.20.0 [MacOSX: amd64]
Compiled at 2019-07-08
Copyright (c) 2006-2019 by Andreas Rumpf

active boot switches: -d:release -d:useLinenoise

@deem0n so I get a lot of warnings with 0.20.xx but no errors. test.nim is still working.
What branch did you use? Can't be master since line 298 does not contain code

zero-functional/zero_functional.nim

Line 298 in b328e7e

I do nimble install:

nimble install --verbose zero_functional

   Success: zero_functional installed successfully.

So I am using tag v0.2.0

this are lines around 298 from my local ~/.nimble/pkgs/zero_functional-0.2.0/zero_functional.nim

 294 proc createCombination*[A,T](it: array[A,T], idx: array[A,int]): Combination[A,T] =
 295   result = Combination[A,T](it: it, idx: idx)
 296
 297 ## iterator over tuples (needed for flatten to work on tuples, e.g. from zipped lists)
 298 iterator items*[T: tuple](a:T) : untyped =
 299   for i in a.fields:
 300     yield i

OK - should be fixed in version 0.3.0

zero_functional.nim(298, 34) Error: return type 'untyped' is only valid for macros and templates
