Re: [Emacs-diffs] master 1758951: lisp/let-alist.el (let-alist): Evaluate `alist' only once.

[Artur Malabarba]

Thanks, I didn't about that. Unfortunately, it seems to not be
available on 24.2 or earlier. (at least, I couldn't find it)

I want to develop this version in parallel with the Elpa version for
now, while there are still a couple of features I'm planning to add.
But I'll add it in later (before release).
