I am now getting this error when running my tests and am now sure what its about:

[FAIL. Reason: Setup failed: cannot call `deal` on precompile 0x0000000000000000000000000000000000000001] setUp() (gas: 0)

Which is this line of code in the tests:

address public constant userAddress = address(0x001); 
...
vm.deal(testAddresses.userAddress, 100 ether);

[Evalir]

We restrict cheatcode calls to certain addresses as it's considered a bad practice—mainly the addresses 0 to 9 which are cheatcodes. You can use makeAddr to make a new address to do deal instead.

Can you expand on why its bad practice, I'm not sure I follow the logic here?

I think this was fixed by #6182, so closing

Originally in #4905 we considered disallowing deal since you typically won’t need to send ETH to precompiles, but you can so we ended up allowing it. Guessing it was accidentally changed in the recent refactor but should be fixed now
