I agree that the wording can be improved. The term "expression" is used here loosely, but should be clarified.
"a+b" with numbers a, b must be handled in order to evaluate complex literals as in "1+1j".
Allowing operator expressions with literals is possible, but much more complex than the current implementation. A simple implementation is not safe: you can induce basically unbounded CPU and memory usage with no effort (try "9**9**9" or "[None] * 9**9").
As for the usefulness, this function is useful to "read back" literal values and containers as stringified by repr(). This can for example be used for serialization in a format that is similar to but more powerful than JSON. |
