Some errors from Get are essentially user error, so we want to be able to recognize them and give the user good feedback on how to proceed. Although sentinel values are not an ideal solution to this, it's something reasonably simple we can do to get this done without lots of refactoring.

// Error is a type used to describe situations that the caller must handle

// The functions and methods that return these specialized errors indicate so

// in their documentation. The Error type should not itself be used directly,

// but rather errors should be compared using the == operator with the

// error constants in this package.

// Values of this type are _not_ used when the error being reported is an
|
|
// operational error (server unavailable, etc) or indicative of a bug in

// this package or its caller.
