 ## Contracts

 ### stdError
 
 This is a helper contract for errors and reverts. In Forge, this contract is particularly helpful for the `expectRevert` cheatcode, as it provides all compiler built-in errors.

 ### stdStorage
 
-This is a rather large contract due to all of the overloading to make the UX decent. Primarily, it is a wrapper around the `record` and `accesses` cheatcodes. It can *always* find and write the storage slot(s) associated with a particular variable without knowing the storage layout. The one _major_ caveat to this is while a slot can be found for packed storage variables, we can't write to that variable safely. If a user tries to write to a packed slot, the execution throws an error, unless it is uninitialized (`bytes32(0)`).

If a user tries to write to a packed slot, the execution throws an error, unless it is uninitialized (`bytes32(0)`).
 
 This works by recording all `SLOAD`s and `SSTORE`s during a function call. If there is a single slot read or written to, it immediately returns the slot. Otherwise, behind the scenes, we iterate through and check each one (assuming the user passed in a `depth` parameter). If the variable is a struct, you can pass in a `depth` parameter which is basically the field depth.

 struct T {

 This is a wrapper over miscellaneous cheatcodes that need wrappers to be more dev friendly. Currently there are only functions related to `prank`. In general, users may expect ETH to be put into an address on `prank`, but this is not the case for safety reasons. Explicitly this `hoax` function should only be used for addresses that have expected balances as it will get overwritten. If an address already has ETH, you should just use `prank`. If you want to change that balance explicitly, just use `deal`. If you want to do both, `hoax` is also right for you.
