# MemoizedValue is a Proc (block) wrapper. It is meant to be used as a
# configuration value. Subsequent `#call` calls return the same memoized
# result.
#
# @example
# num = 19
# value = Pry::Config::MemoizedValue.new { num += 1 }
# value.call # => 20
# value.call # => 20
# value.call # => 20
#
# @api private
