Add this line to your application's Gemfile:

This module refines Array class.

To use this, first, you should write this where you wannna use

using ImmutableArray

Override << operator for Array class objects, and set symbolized method after it.

some_array << :method_name

I made this gem to make completely frozen Array.

To do this,

using ImmutableArray

arr = [1, 1, 2, 3, 5, 8]

arr << :freeze # arr becomes completely frozen

That's all.
