No. It says where to assign on the left hand side and what to assign

Because

|count += 1

could easily be parsed as

|count := 1

on the first glance. You have to look harder to see that this is *not*
an assignment.

I don't decide to change a name, I decide to change a construct.

And you probably heard about: Ada is for ease of reading, not writing.
