Hi there, I was going through the docs and had a quick question regarding `let` keyword.  
Typical usage:

```julia
let a=1, b=2
  println("a: $a, b: $b")
end

```

Which parses to:

```julia
(let println("a: $a, b: $b") (= a 1) (= b 2))

```

My question is, why can’t `let` take `kwargs...` as well?  
I haven’t looked into macros much but I think it would be possible to allow for the following:

```julia
d = Dict("a"=>1, "b"=>2)
let d...
  println("a: $a, b: $b")
end

```

You’d have to include a `kwargs` like construct similar to `function`  
Apologies if this a basic question, just wanted to know the rationale

I’m pretty sure this cannot work as `let` is syntax construct (and not a macro either), i.e. it has only access to the code and not runtime values of variables.
