Feature request: as-> highlighting

[tanzoniteblack]

I was recently having to write a rather complex set of threading code with as-> and it occurred to me that it would be useful if in an as-> sexp, we set the font-face of the name of the bound value to a different font face than normal so that it stood out a bit.

Example:

Instead of

(as-> {:cat 5} x
  (reduce some-fn
          x
          (mapcat someother-fn some-val))
  (assoc x :dog 27)
  (map weird-fn x)
  (map x some-coll))

font-locked x with some special font-face so we can make it stand out to make it easier to quickly parse out this information.

I would consider this to be very low priority, but might be a nice to have.

In that same thread, we could font-lock let-binds too. It's all a matter of developer time. :-)

Indeed. I wouldn't add special font-locking for the bound variable here, unless this is something that we've done consistently everywhere else. (unlikely to happen unless someone volunteers to work on it).
