**Shadowing**

Note: This explanation uses two informal terms, stomping and **shadowing**. They are not official concepts in the Go language spec.

Like many programming languages, Go has mutable variables: assigning to a variable changes its value.

When using short variable declarations with the := operator, in some cases a new variable is not created. We can call this stomping. It’s OK to do this when the original value is no longer needed.

Be careful using short variable declarations in a new scope, though: that introduces a new variable. We can call this **shadowing** the original variable. Code after the end of the block refers to the original. Here is a buggy attempt to shorten the deadline conditionally:
