    # * +convert_options+: When creating thumbnails, use this free-form options
    #   field to pass in various convert command options.  Typical options are "-strip" to
    #   remove all Exif data from the image (save space for thumbnails and avatars) or
    #   "-depth 8" to specify the bit depth of the resulting conversion.  See ImageMagick
    #   convert documentation for more options: (http://www.imagemagick.org/script/convert.php)
    #   Note that this option takes a hash of options, each of which correspond to the style
    #   of thumbnail being generated. You can also specify :all as a key, which will apply
    #   to all of the thumbnails being generated. If you specify options for the :original,
    #   it would be best if you did not specify destructive options, as the intent of keeping
    #   the original around is to regenerate all the thumbnails when requirements change.

# The goal is to not use the regular Symbol#to_proc
# (which is to_proc method in the Symbol class)
# but rather use an Abstract Syntax Tree transformation to
# transform map(&:to_s) into map {|x| x.to_s}
# This can be achieved by using the flexible compiler architecture
# in Rubinius and is presented below.
#
# First we undefine the regular Symbol#to_proc
