-can only be compiled by specifying a hardfork using the `--hardfork` flag (with the latest hardfork available as the default option) strictly after `London` and equal or older than `Cancun`. Non-closed ranges can also be used, as well as specific versions (e.g. `%hardfork(">london")`, `%hardfork("cancun")` and `%hardfork(">=cancun,<=cancun")` are all valids.`).
