   Unrelated side note, I love that github markdown syntax highlighting understands zenscript as a language.

   ZS supports the idea of varargs.
   However, currently only methods that are declared in the Java Code allow for varargs.

   Custom functions in ZS are still pretty limited. They do not allow for varargs.
   Heck, normal functions don't even allow for overloading or optional parameters.

   If you are looking on how to use varargs when in Java Code, you can see here

   Since varargs are just syntactic sugar for an array creation, you can create the array explicitly.
   Or you could create a zenClass inside ZS code, and have overloads for the most cases, so something like

   zenClass MyClass {
       zenConstructor(){}
       function doSomething() as void {doSomething([]);}
       function doSomething(arg0 as string) as void {doSomething([arg0]);}
       function doSomething(arg0 as string, arg1 as string) as void {doSomething([arg0, arg1]);}
       function doSomething(arg0 as string, arg1 as string, arg2 as string) as void {doSomething([arg0, arg1, arg2]);}
       function doSomething(arg0 as string, arg1 as string, arg2 as string, arg3 as string) as void {doSomething([arg0, arg1, arg2, arg3]);}
       function doSomething(varargs as string[]) as void{
           /*Code here*/
       }
   }
