Description

I'm experiencing a problem when I chain another iterator method closure after collectMany. The parameter type of the closure on the following method should be the element type of the list returned by collectMany and when using dynamic Groovy this works fine. The static type checker thinks the closure parameter should be List and is failing to compile.

See attached example.
