I think it's a lot less clear exactly where the variable is being imported to
that way. Would you still be able to overwrite $outer as a normal local
variable in that function scope? Would it return to its captured value every
time the function runs? It's different from capturing into a function, because
you're not just adding a variable to a single existing scope.
Just allowing the captured var for property initialisation would be less
ambiguous, but having to list it in use() and then in the property list would
be the same amount of code as you can currently get to with constructor
promotion (see my first example in the thread).
From what Ilija has pointed out, the implementation of actually getting the
values into the right place is going to be harder than handling the syntax
anyway. My current feeling is that if it's possible at all, it will end up as a
shorthand for that constructor example: declaring normal properties, and
populating them as the instance is initialised.
