Foundry:

• it is easier to pass the whole contract instance e.g.

flashLoanerPool = new FlashLoanerPool(address(dvt)); then fetching the address back

address(flashLoanerPool)

• public variable in contract can be reached by calling as a function
  • even the function inside the variable (type contract)
    • e.g. theRewarderPool.rewardToken().balanceOf(users[i])
