def initialize(${1})
  <split ${1} by comma and for each split>
    @{split} = #{split}

end

# So that some thing like this `def initialize(a, b)` would result

def initialize(a, b)
  @a = a
  @b = b
end

# and for `def initialize(a, b, c)` would result

def initialize(a, b)
  @a = a
  @b = b
  @c = c
end
