quick observation, in above function (attached image),

it will always return *Valid&lt;B&gt;* and *NEVER* *Invalid&lt;Nel&lt;A&gt;&gt;, even if all are either.lefts, it will just return Valid&lt;EmptyList&lt;B&gt;&gt; losing all the errors, r8?*

is there a prebuilt function to compute over *List&lt;Either&lt;A,B&gt;&gt;* to return *Valid&lt;List&lt;B&gt;&gt;*
*if* *ANY* f(a) returns a value, *else Invalid&lt;Nel&lt;A&gt;&gt;?*

I think I will need to manually traverse and collect errors until I reach an Either.Right, and if before end I do reach an Either.Right then only care about those and return *Valid&lt;List&lt;B&gt;&gt;* *else* if not then return all accumulated errors as *Invalid&lt;Nel&lt;A&gt;&gt;*

*r8?*
