Subject: 24.4; let-alist does not handle vectors
Date: Fri, 08 Apr 2016 13:13:15 +0200

This construct does not work (gives error "(void-variable \.a)"):

(let-alist '((a . 1) (b . 2))
  `[,(+ .a .b)])

while this construct returns the expected [3]

(let-alist '((a . 1) (b . 2))
  (+ .a .b)
  `[,(+ .a .b)])

The problem seems to be that let-alist--deep-dot-search skips vectors.

I bumped the version to 1.0.6, so the fix should appear on ELPA soon.
