Daniil Ovchinnikov commented on GROOVY-8214:
--------------------------------------------
All cases work when value returned from property is a {{Closure}}. In
{{Closure}} cases explicit method takes precedence:
{code}
class A {
def getFoo() { return { "closure" } }
def foo() { "method" }
}
println new A().foo() // method
{code}
I see no reason not to allow the same behaviour for all objects with
{{.call()}} defined.
There is special handling for closures in
{{groovy.lang.MetaClassImpl#invokePropertyOrMissing}}. In may be replaced with
something like this (pseudocode):
{code}
if (/*necessary checks*/) return invokeMethod(value, "call", args)
{code}
> Implicit .call is inconsistent
