---------------------------------------------------------------
What’s clunky? The plus sequence? The spread into list in the example creates a
list. Then you as into an array. -Now that I look at it, you should be able to
just use *A as your argument expression.-
{code:groovy}
@CompileStatic
class Groovy11060 {
public static final List<String> A_LIST = ['a1', 'a2']
static void varargs(String... strings) {
println Arrays.toString(strings)
}
static main(args) {
varargs(*A_LIST) // error -- could be fixed for Iterable<String> to
String...
varargs(A_LIST as String[])
varargs(A_LIST.toArray(new String[0]))
}
}
{code}

> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 4.0.12
> Reporter: Christopher Smith
> Priority: Major
>
> Spreading a list inside brackets causes a {{SpreadExpression should not be
> visited here}} during class generation. (The business instance of this is
> trying to use a list of URL patterns for Spring {{antMatchers}}.)

> println Arrays.toString(strings)

> public static void main(String... args) {
> varargs([
> *A
