Hey,
Have you ever wondered *what it means* for an object to be mutable and *why*
do we even have mutable objects in Ruby? I wrote an article that explains
that and a lot more, including upcoming changes to String mutability that
you *should be aware* of.

Here it is:
http://www.blackbytes.info/2016/01/ruby-mutability/

Please let me know what you think :)
