tryExceptElse.sol

```
// This code snippet shows how an external function can use a pattern like
// python's `try..except..else` with `.call`, `throw`, and reentry

contract TryExceptElsePatternUser {
    address _sender;
    function tryExceptElsePatternExample()
        external // must be external
    {
        if( msg.sender == address(this) ) {
            // `try` body - runs at +1 depth, msg.sender is this, true sender in storage
        } else {
            _sender = msg.sender;
            if( !this.call(msg.data) ) {
                // `except` body, run if "try" body throws
            } else {
                // `else` body - run if there is no exception
            }
            // EDIT: `finally`? body? I think it is not correct but can't remember why
        }
    }
}
```

Perhaps because finally has to perform non-conditional clean-up and then forward the exception (if any). It is not clear how to perform such a feat.

Just guessing. CMIIR

@nmushegian do you think this will work with latest EVM?
