[documentation] <Scope Issue in Example Code for retrieval and type-assertion>

[apxamccallum]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

sessions/doc.go

Lines 140 to 145 in bb4cd60

	// Retrieve our struct and type-assert it
	val := session.Values["person"]
	var person = &Person{}
	if person, ok := val.(*Person); !ok {
	// Handle the case that it's not an expected type
	}

In this example val.(*Person) will not be assigned to person as it is outside of the if statement scope.

Suggested Correction

// Retrieve our struct and type-assert it
val := session.Values["person"]
person, ok := val.(*Person)
if !ok {
	// Handle the case that it's not an expected type
}
