Eric Milles commented on GROOVY-10914:
--------------------------------------
You can cast at the point of assignment to stop this: "def y = (LongStream)
...". This is how I write it to prevent repeating the type when I need to shut
down flow typing.
> Method ambiguity error even if the given argument has an explicit type
