I afraid so Java syntax isn't good  inspiration

they use symbol ... like specific synonym to [].
public Method getMethod(String name, Class... parameterTypes)

I didn't find any info about vararg in Oracle - it uses collection and
it allows implicit constructors for emulation o variadic functions -
but "variadic" argument isn't scalar too. So I invite any opinions
about it.
