Ruby List Method - Simple: The Ruby Library

So I've been developing a Ruby library to speed up as well as clean up my Code and well here is my list() method, it can take direct parameters or an array and display them as a list. It works with a number of other Methods i have built.

Code:
def list(*simple_args)
	if !simple_args[0].kind_of?(Array)
		if simple_args.length > 0
			simple_get_last_list_item = simple_args.length - 1
			simple_count = 1
			for simple_list_item in simple_args
				if simple_count < simple_args.length
					puts simple_args[simple_get_last_list_item] + " " + simple_list_item
					simple_count += 1
				else
					break
				end
			end
		else
			puts("\nSimple Error: List, must pass at least 2 parametes (List item, formate sytle.) or Array and formate style.")
		end
	else
		if simple_args[0].length > 0
			simple_get_last_list_array_item = simple_args[0].length - 1
			simple_count = 0
			for simple_list_array_element in simple_args[0]
				if simple_count < simple_args[0].length
					puts simple_args[1] + " " + simple_args[0][simple_count]
					simple_count += 1
				else
					break
				end
			end
		else
			puts("\nSimple Error: List, must pass at least 2 parametes (List item, formate sytle.) or Array & formate style.")
		end
	end	
	return
end

An example of this method in use, I've also used some of my other library methods to show just how clean and organised it all looks together:

Code:
load 'simple.rb'

names = ['John','David','Alice']
if is_array(names)
	list(names, '+') 
else
	simple_error('In this instance array must be passed.','Simple Error')
end

display_errors('all')

Also works like: list('John','David','Alice', '+')

How it would look,

Code:
names = ['John','David','Alice']
if names.kind_of?(Array)
	names.each_line do |element|
		puts('+' + element)
	end
else
	puts('Simple Error: In this instance array must be passed.')
end

Not to mention this example has no error handling, it simple puts them out as they happen.
