Hi, Levi,
Thanks for your opinion.
Why don't reverse mode ?.
'inout' is created with the three characteristics:
- Check type of out is equal to type of param
- Avoid modifying caller variable value when the function throws an exception.
( Like inout of Hacker language )
- Allow explicit call-site pass-by-reference annotation.
Then, current references are deprecated and after than, in other version, they
are removed.
In this way, projects can be adapted gradually
