is there a method to filter SafeMath for calculations of int256

like using SafMath for int256; ?

which is not possible with openZepplin's SafeMath.sol whic only operates on `uint`s

there's this note in the page of SignedSafeMath at openZeppelin's website that says:

"SignedSafeMath is no longer needed starting with Solidity 0.8. The compiler now has built in overflow checking. "

could anyone correct that I don't need to use any extra library to operate calculations, so I can use standard arithmetic operators without worry of overflow explosion? (Y/N)

Make sure to get the solidity version right, else there'd be screw ups
