Describe the bug

I have not been able to call deal on DIGG token (0x798D1bE841a82a273720CE31c822C61a67a601C3) with error

    }

    function testDealDigg() public {
        deal(0x798D1bE841a82a273720CE31c822C61a67a601C3, address(1), 100);
    }

As you can see in L589 of the implementation, the DIGG contract's balanceOf method dynamically computes the balance to return (like a rebase token), whereas the deal cheat only supports tokens that return balanceOf by reading a value directly form a storage slot, because deal works by changing the value in the balanceOf storage slot. As a result this token is not currently supported by forge-std, similar to #140

As a workaround you can find an DIGG whale from etherscan, prank as that user, and transfer tokens to any address you need.

Going to close as a duplicate of #140
