Vladimír Oraný created GROOVY-8276: --------------------------------------
Summary: `.&` should return `MethodClosure` instead of just `Closure` Key: GROOVY-8276 URL: https://issues.apache.org/jira/browse/GROOVY-8276 Project: Groovy Issue Type: Improvement Components: Compiler Reporter: Vladimír Oraný if you get method handle using `.&` notation the retrieved object is of type `Closure`. It should be method closure instead. Following code should compile: {code} @CompileStatic void doSomething(MethodClosure methodClosure) { this.doSomething(this.&doSomething) } {code} One of the use cases I'm currently working on is a type-safe DSL which accepts method closure to test given method. I would like to be sure that none passes in regular closure. At the moment, I need to do {code} if (!(method instanceof MethodClosure)) { throw new IllegalArgumentException("Closure must be method closure. Use object.&methodname to get type safe method closure!") } {code} To achieve similar behavior. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
