OK. Let me be a bit more specific. I think (forcing myself to be a bit
more analytic than I have been up to now) my main objection is that the
variadic part of the parameters should be marked explicitly in the
formal parameter list.

I don't mind having it limited to a single typed array - as you say we
probably don't want someone implementing sprintf.

But if I have

  foo( a text, b int[])

it looks odd if both these calls are legal:

  foo('a',1,2,3,)
  foo('a',ARRAY[1,2,3])

which I understand would be the case with the current patch.

I'm also still curious to know how the following would be handled:

  foo(a text[], b text[])

cheers
