in lua you can do somthing like

Code:

function printEveryArg(...)

    for _, item in pairs( arg ) do

    io.write(item.."\n")

    end

end

so the function can take any number of args,
How do you do this in ruby?
I cant seem to find out anywhere..

Code:

def printEveryArg(*args)

    puts args.join("\n")

end

(args is a standard ruby array)
