My personal experience with "var"s - they are used a lot in Scala, for
example - is they make code very unreadable, especially when working
with collections and streams. The only case when a "var" is suitable is
new object creation:
var object = new SomeType()
In all other cases they are more painful than valuable.
I can say it differently. It's very easy to use "var"s wrong. No matter
what style guides are available, people will often use them in a way
that makes code less readable.
