It's almost as messy as putting all the functions into each other.
mmh, seems to me that just replacing function by fn and having such a different behaviour is risky
Auto capture by-value is clear enough with a single expression closure, but I think for multiple statement functions it could be confusing to have to keep track of scope. Being explicit (with use()) makes it simple and concise.
If this were to pass, I think the syntax should continue to include the arrow to signify the auto capture by-value intention. Just like in JavaScript, the arrow is used whether single expression or multiple, and the use of brackets is what separates them.
The 'use' statement clarifies the scope for me. So a proposal like this could have the side effect of mixing scope which would lead to a confusing code.
