# Date memoizes some instance methods using metaprogramming to wrap
# the methods with one that caches the result in an instance variable.
#
# If a Date is frozen but the memoized method hasn't been called, the
# first call will result in a frozen object error since the memo
# instance variable is uninitialized.
#
# Work around by eagerly memoizing before freezing.
#
# Ruby 1.9 uses a preinitialized instance variable so it's unaffected.
# This hack is as close as we can get to feature detection:
