New scope solution

[tkf]

@StefanKarpinski

• for , while , try - catch - finally , let , comprehensions, broadcast-fusing,

All scope-introducing constructs that occur outside of a function body.

Is it possible to exclude let? It will be very useful for requesting a clean namespace and “plain” scoping rule. I know I can write

(function()
    x = 0
    for i in 1:10
        x += i
    end
    x
end)()

but it feels like I’m writing javascript.
