module Decidim
# This class acts as a registry for any code blocks with names and should be
# used as a singleton through the `Decidim` core module. This allows
# registering code blocks for different use cases, for example for the
# authorization transfers.

#
# @return [Hash<Symbol => Proc>] A hash of the currently registered blocks
# with their keys as the hash keys and the blocks as the hash values.
