>                 Key: GROOVY-8212
>                 URL: https://issues.apache.org/jira/browse/GROOVY-8212
>             Project: Groovy
>          Issue Type: Bug
>          Components: Static compilation, Static Type Checker
>    Affects Versions: 2.4.10
>            Reporter: Christopher Smith
>            Assignee: Eric Milles
>            Priority: Minor
>
> When a GString is used as the key for a bracket-style map get (in this case, from an overly verbose CSV file):
> {code}
> row["$param URL"]
> {code}
> the {{GStringImpl}} object is passed directly to {{Map#get(Object)}}. Since GStrings are never equal to Strings, this means that the get will always return null.
> If {{row}} is explicitly declared as a {{Map<String,?>}}, however, Groovy ought to identify the intended behavior (using a templated string as a map key) and use the string value instead.
> The current behavior is a problem because even in static compilation mode, where the generic key bound is known, Groovy does not complain about the use of a GString here (because it normally treats GStrings as valid for {{String}} targets?), but the lookup will fail at runtime.
