// that returned the error originally and the parameter type that was deemed
// invalid.

// Example:
//
// // err is of type InvalidParameterError
// _, err := expression.Name("foo..bar").BuildOperand()

// This error is returned if opaque structs (ConditionBuilder, NameBuilder,

//
// Example:
//
// // err is of type UnsetParameterError
// _, err := expression.Builder{}.Build()
// _, err := expression.NewBuilder().
// WithCondition(expression.ConditionBuilder{}).
// Build()
