Return a value of an "unspecified bool" type that evaluates to `false` if this shared pointer does not refer to an object, and `true` otherwise. Note that this conversion operator allows a shared pointer to be used within a conditional context (e.g., within an `if` or `while` statement), but does _not_ allow shared pointers to unrelated types to be compared (e.g., via `<` or `>`).
