Overview

Convenient syntax for expressing operators in statement condition blocks. For example, the following:

policy.allow.where(:s3_prefix).not("forbidden").
  where(:current_time).lte(Date.today+1)

is equivalent to:

conditions = Policy::ConditionBlock.new
conditions.add(:not, :s3_prefix, "forbidden")
conditions.add(:lte, :current_time, Date.today+1)
policy.allow(:conditions => conditions)
