> property semantics of map-based types (pt.2)
> --------------------------------------------
>
> Key: GROOVY-11403
> URL: https://issues.apache.org/jira/browse/GROOVY-11403
> Project: Groovy
> Issue Type: Improvement
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Labels: breaking
> Fix For: 5.0.0-alpha-9
>
>
> The property semantics for map-based types was recently updated (see
> GROOVY-11367). {{testRead3()}} and {{testRead4()}} demonstrate the desired
> outcome: public members (except {{isEmpty()}} and {{getClass()}}) then map
> get/put.
> {{testRead1()}} and {{testRead2()}} demonstrate the differing semantics for
> {{this}} references: accessible fields and public methods then map get/put.
> Why the difference between fields and methods? Also there are differences
> between dynamic and static compilation modes (as noted).
