Paul King commented on GROOVY-11185:
------------------------------------
I agree it does look unexpected but the transpose method doesn't have any type
information that the static compiler could use, so maybe we do extra checks
now. In any case, it looks related to GROOVY-11090.
Workaround is to not use @CompileStatic.
> each after transpose with 2 arguments does not compile
