closure-pass is a crate for passing arguments to a closure with capture feature of C++ lambdas.

Usage

So far, this crate requires two nightly features: stmt_expr_attributes and proc_macro_hygiene. Usage is pretty straightforward, the following code:

```rust let a = /../; let b = /../;

[closure_pass(a, b = b.f()]

move || { // .. } ```

Will expand to something like:

```rust let a = /../; let b = /../;

{ let a = a.clone(); let b = b.f(); move || { // .. } } ```
