-----------------------------
> Cast short-hand breaks for empty map
> ------------------------------------
>
> Key: GROOVY-8778
> URL: https://issues.apache.org/jira/browse/GROOVY-8778
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 3.0.0-alpha-3
> Reporter: Paul King
> Assignee: Paul King
> Priority: Major
> Labels: breaking
> Fix For: 3.0.0-alpha-4
>
>
> We support:
> {code}
> println Date[time:0]
> def map = [time:0]
> println Date[*:map]
> map = [:]
> println Date[*:map]
> {code}
> but not:
> {code}
> println Date[:]
> {code}
> This is a breaking change since we currently support printing an empty map without brackets but would require them after this change:
> {code}
> println [:]
> {code}
> would need to be:
> {code}
> println([:])
> {code}
> But we require the brackets for lists (empty and non-empty) and non-empty maps already.
