Aleks Tamarkin commented on GROOVY-11188:
-----------------------------------------
[~paulk] I noticed that transpose for *Array* returns an *Array[][]*
[https://github.com/apache/groovy/blob/e2ff7dbe3f82c9f8fbdd7186184f8530fb6b55b2/src/main/java/org/codehaus/groovy/runtime/ArrayGroovyMethods.java#L8541]
But transpose for *List* takes and return a flat *List*
[https://github.com/apache/groovy/blob/e2ff7dbe3f82c9f8fbdd7186184f8530fb6b55b2/src/main/java/groovy/util/GroovyCollections.java#L165]
Should transpose for *List* take and return a *List<List>*
> CompileStatic broken for transpose lists in 4.0.14 but works in 4.0.13
