Previously the variable and lexical environments were already kept in a NativeFunction call. However when we (try to) call a private method from within an async function we go through async_block_start which sets up a NativeFunction to call. This is technically not exactly as the spec describes it, as that requires you to actually "continue" the context. Since we don't have that concept (yet) we use this as an implementation detail to access the private environment from within a native function. Note that this not allow general private environment access since most things get blocked by the parser already.
