<overview>
<p>When a local variable is defined with the same name as a built-in type or function, the local
variable "shadows" or "hides" the built-in object. This can lead to
confusion as a reader of the code may expect the variable to refer to a built-in object.
</p>

</overview>
<recommendation>

<p>Change the name of the local variable so that it no longer matches the name of a built-in object.
