Where can I find the security enhancement of solc compiler? Its a time saver so that you can write some code, automatically run script that sets state of the contract - thus allowing you to quickly understand how the code is working. // Chose which contracts should be analyzed as the deployed one. Additionally, `*` can be used as a wildcard to request everything. In a similar to way to ERCs and as we work towards to more interoperable smart contracts, being able to quickly examine those interfaces that you want to integrate is a time saver. 2 below).
