Thanks, it's good to have a clear use-case.  You might want to mention
it in the commit message (tho at least now it's in the associated bug thread).
How often/much do we care about the printed form of `let-alist` expressions?
Maybe limiting the effect to ". at the beginning of symbol doesn't need
to be a escaped if the second char is a letter" would be good enough?
