Package: emacs
Version: 23.2+1-5.1
Severity: wishlist
X-debbugs-cc: Jonas Bernoulli <jonas@bernoul.li>

I would be nice if the progress indicator library map-progress.el by Jonas
Bernoulli. were included in Emacs

The code repository is at:

    https://github.com/emacsmirror/map-progress/blob/master/map-progress.el

;;; Commentary:

;; This library defines mapping macros that report progress.

;; For many of the standard and CL mapping functions like `mapc' macros
;; like `mapc-with-progress-reporter' are defined here.  The arguments
;; have the same meaning as the respective arguments of the respective
;; function and `make-progress-reporter', which ever has an argument by
;; the same name.

;; Even when the respective function supports multiple sequences the
;; macros defined here only support one.  One the other hand all of the
;; `make-progress-reporter' arguments except for MESSAGE are optional.
;; This includes the starting and final state argument.

;; Any mapping function with only exactly two mandatory arguments - a
;; function which is applied to a sequence - are supported by
;; `map-with-progress-reporter' which can be used when no specialized
;; macro corresponding to a particular function exists, but additional
;; arguments are not supported.

;; Therefor at least the following functions are not supported: `map'.
;; However support for the following divergent mapping functions has
;; been implemented: .

;;; Code:
