Here, you are using a form of parameter expansion that intrinsically performs
variable assignment, only to redundantly assign the result of the expansion to
the same variable once again. In a roundabout fashion, it ends up proving
Greg's point. I'd suggest temporarily disavowing yourself of the
${parameter:=word} form, for the time being.
