Paul King commented on GROOVY-8703:
-----------------------------------
This is by design as per a requested behavior. From the GroovyDoc:
"... If no arguments with @NamedParam or @NamedDelegate annotations are found
the
first argument is assumed to be an implicit named delegate ..."
I guess assuming all of them were @NamedParam would be the alternative we could
have had.
I guess we could make a boolean \{{autoDelegate}} annotation attribute to swap
between those behaviors.

> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.5.1
> Reporter: Eric Milles
> Priority: Major
>
> Tried this example and got cast exception converting Map to Integer. Should
> the print statement at the end use the generated map constructor as expected?
> (Note: I am compiling with indy variant; tried to use web console to try
> vanilla MOP...)

> @NamedVariant @VisibilityOptions(Visibility.PUBLIC)

> this.r = r
> this.g = g
> this.b = b
> }
> public static final Color BLACK = new Color(0, 0, 0)

> print(new Color(g:12, b:42, r:12)) // gives
