FYI: this is a bug fix. Analyzer used to think all variables in methods were
mutated in closures, regardless of whether any closures actually existed :) 
(they were missing visitMethodDeclaration, so it thought the result= assignment
in the else branch was in a closure when it compared against the
_enclosingFunction, which was incorrectly `null`)

+          result[core.$length] = this.length;
         } else {
           result = new (core.List$(E))(this.length);
         }
