             Summary: Newify transform docs missing support for local variable declaration
                 Key: GROOVY-8275
                 URL: https://issues.apache.org/jira/browse/GROOVY-8275
             Project: Groovy
          Issue Type: Documentation
          Components: xforms
            Reporter: Eric Milles
            Priority: Minor


Javadocs and online documentation for the Newify AST transform is not quite clear in a couple instances.

1) Online docs http://groovy-lang.org/metaprogramming.html#xform-Newify Ruby-style section could be more clear IMO if the {{([Tree,Leaf])}} were removed since it only enables the Python-style expressions.

2) Javadoc and online docs do not mention that {{@Newify}} can be applied to a local variable declaration, like: {{@Newify def o = Object.new()}}.

3) The scoping of the transform is pretty clear for the class, method and field/property cases.  However for the local variable case, it appears that the transform applies throughout the containing scope of the local variable.  That is, I can use the extra constructors anywhere in the block to re-initialize the variable.  {{@Newify def o = Object.new(); ... o = Object.new() ...}}.  Is this the intended behavior?  My intuition was that the initializer expression was the only place the transform applied, like in the case of a field.
