Mutable with logic inside or immutable with logic outside?
I know immutable objects are preferred to mutable objects for reasoning and maintenance. But in occasions making a class immutable have some costs, let me explain it with a simple example:

Are any side effects not concrete side effects?
In Chapter 23 of “Object Oriented Software Construction” (1988), Betrand Meyer makes a distinction between side effects, concrete side effects, and abstract side effects.

Side-effect free programming language for reproducible data transformation
Is there a usable programming language that disallows all side effects except for its input stream (aka STDIN) and its output stream (aka STDOUT)? All executable scripts in the language should be guaranteed to produce exactly the same output when given the same input (unless they don’t terminate soon enough). This excludes any other external state such as:
