WebJun 24, 2016 · In other cases where behavior is unreliable, Solidity does not expose it. (For instance, there is no way to call an external contract and retrieve the return value if the signature is not known ahead of time.) The "escape clause" is in-line assembly, which allows the creation of libraries to do anything expressible as EVM assembly.
