Why not keys instead of many accessor functions?

See `helm-file-attributes' in helm-utils.el at
https://github.com/emacs-helm/helm

(helm-file-attributes "~/.emacs.d/emacs-config-laptop/.emacs.el" :size t)
=>62675
(helm-file-attributes "~/.emacs.d/emacs-config-laptop/.emacs.el" :human-size t)
=>"61.2K"
