There's a pretty good reason for this one, I think. The two statements:

  Text += "Some new text\n"

look sort of analogous. Both seem to be taking an object and performing
a method on it. But strings are immutable; you can't perform any method
on it to change the string. The syntax

  Text = Text + "Some new text\n"

makes it clear that we're creating a new object out of an old one, and
assigning it to the variable "Text".

Sure, you could interpret += to mean the same thing, but I think it
would be less clear to those trying to learn the language. It's critical
to get people out of C mindsets in order to be able to understand
what people mean when they say "everything is a reference."
