------------------------------------------
Summary: Set coercion doesn't "pull through" method resolution
Key: GROOVY-10809
URL: https://issues.apache.org/jira/browse/GROOVY-10809
Project: Groovy
Issue Type: Bug
Components: Static Type Checker
Affects Versions: 4.0.6
Reporter: Christopher Smith
In the usual case, the brackets syntax for an inline collection is implemented
as an {{ArrayList}} but can become {{LinkedHashSet}} if the expression type is
determined to be {{Set}}. However, this doesn't work if {{.asImmutable()}} is
applied, because the expression is definitively identified as {{List}} first.
{code:groovy}
Set<String> WORKS = ["a"]
Set<String> ALSO_WORKS = (["b"] as Set).asImmutable()
Set<String> FAILS = ["c"].asImmutable()
{code}
