Subject: a, b = Array.new(2).map!{|x| data.dup}

I think I can replace this code

@scr = @output.dup
@png = @output.dup
@pdf = @output.dup
@svg = @output.dup
@ps = @output.dup

with this equivalent:

@scr, @png, @pdf, @svg, @ps = Array.new(5).map!{|x| @output.dup}

Is there a nicer variant available?

(Of course @scr, @png, @pdf, @svg, @ps = @output.dup will not work, I
need 5 independent instances.)

Thanks,
