Return as variable

[bvssvni]

Dyon allows you to assign a value to return, as if it was a normal local variable:

fn foo() -> {
     return = 4
     return = 5
     // will return 5
}

This requires -> on the function.

The return value outlives the arguments of the functions, unless they have a lifetime. If you assign to it, the right expression must outlive 'return.
