BTW, its works perfectly, with that i can decide what parameter return
in advances, (but, yet, I dont know is a good idea or not)

Thanks

module Kernel
def before (name, &block)
define_method(name) do
if block.arity == 1
yield nly_one
elsif block.arity == 2
yield ne,:two
elsif block.arity == -2
yield ne, :a , :splater, :argument
end
end
end
end

class A
before :foo do |first|
puts first
end
end

a = A.new
a.foo

class A
before :foo do |first , second|
puts second
end
end

a2 = A.new
a2.foo

class A
before :foo do |first , *splat_arg|
puts splat_arg
end
end

a3 = A.new
a3.foo
